Go vs. Rust: Which One to Pick for Web Development?

Every web developer has asked themselves this question, and some others still do, even after reaching their conclusion. Go vs. Rust: Which one to pick for web development?  Or, in 2022, should you use Golang or Rust?

These are the most recent programming languages to be used today. Go was introduced by Google in 2009, and Mozilla introduced Rust later in 2010.

The two languages are big initiatives from web development titans, Google and Mozilla, respectively, designed to address the shortcomings of existing programming languages. The popularity rivalry between Go and Rust is fierce.

Go was inducted into the TIOBE Index Programming Language Hall of Fame in 2016 as the programming language with the biggest year-over-year increase in search request ratings.

In addition, according to Go’s own survey, 92% of developers are delighted with their development experience and intend to utilize the programming language in future projects.

On the other hand, Stackoverflow’s 2020 Developer survey shows that the Rust language has been the most popular for years. More than 86% of developers said they would prefer to work with Rust again in the foreseeable.

The selection of the appropriate web-development technology is critical to the success of a business. Out-of-date technologies may turn off prospective clients. As a result, if you want to employ the latest modern technology currently on the market, we suggest you try Go or Rust.

What Is Go?

Golang – Image Source: Mobcoder

Go is a statically typed, executable programming language that is sometimes stylized as “Golang.” The language, created by Google engineers and based on C, was created to compete with C++. Due to its simple syntax, Golang is sometimes compared to Python.

The language is intended primarily for building scalable small applications and online APIs, particularly with its goroutines. 

The Golang language easily assembles to machine code, offers the convenience of garbage collection (GC), and has the ability to represent run-time.

By distributing tasks over several CPU cores simultaneously, the syntax of goroutines makes it simple for programmers to design programs that can fully dominate concurrency, such as huge eCommerce platforms.

It is, therefore, ideal for a parallel computing environment, to put it exactly. Another Go component that ensures efficient memory management is garbage collection. As a result, objects that are no longer used are “trashed” from memory to make room for new ones.

Advantages of Go for Web Development

You should presumably know what Golang has in store before deciding which language to pick for web development. Let’s examine a few advantages of using Go.

1. Go is a really fast language

Golang does not necessitate an interpreter and may be quickly translated into machine instructions. Because of this, there is less need for intermediary phases, which leads to faster development.

The Go language is always a proactive language compared to Java when it comes to latency and high.

2. It is a thriving developer environment

Increasingly programmers like Golang over other languages since it is a very quick language. Go is the major language used by over 1 million professional Go developers. 

If we take into account developers and designers who mostly work with other computer languages but sometimes use Go, the figure may be higher than 2 million. It is predicted that this number will increase too much in the long term.

3. Go produces extremely readable code

Go takes its readability from Python but borrows the run-time efficiency of C. The average programmer can easily learn the Go syntax, especially if they speak English well. 

Gofmt automatically adjusts surface-level elements like indentation and spacing. Additionally, golint performs further style checks. Because Go is so user-friendly, newbies gravitate toward it right away.

4. Golang is adaptable

Scalability is typically a key factor when selecting a piece of software for an organization. Several scalability options are available with Golang. 

It enables the execution of a wide range of skills at a certain point. If you choose to, you could use Golang for a very long period.

5. It is easy to learn the Go language

This is not a command-line tool that takes months to master. If you’re a beginner, you’ll have no trouble understanding sentence structure. The programming model of Go is comparable to that of C. Learners won’t be perplexed by arguments or interactions in Golang.

When Is It Advisable To Utilize Golang?

The Go programming language may be used for many different types of applications.

According to Go’s 2019 report, the most common area by far was web development (66%), but other common areas included databases (45%), network programming (42%), systems programming (38%), and DevOps tasks (37%).

The majority of Go developers believe that because of its propensity for concurrency, Go has a preference for networking services.

Golang is often praised as the best language for server-side development. More than you would imagine, quick page execution is essential to building brand recognition online.

The Google Cloud Platform is also officially supported by the language. A wide range of services is provided by Google Cloud, many of which include the idea of cloud computing. Therefore, Go excels when it comes to high-performance cloud applications.

An abridged use case for Golang is shown below.

Golang use cases

• Web-based programs. It is ideal for handling HTTP requests since it supports many concurrent users and uses fewer resources.
• CLIs and scripts: The majority of CLIs utilize Go, such as kubectl.
• Applications for streams. Using Go routines, Go can handle millions of events very quickly. 
• Cloud-based and serverless apps. Go is a fantastic option for Serverless tasks, particularly on Google Cloud.
• Microservices. Go is a fantastic option for cloud-native microservices due to its compact design, speed, and monitoring features.

What Is Rust?

With the aid of various programming models, Rust is a constructed, statically typed programming language. 

Performance and safety were given priority while developing the language, with safe compliance being the main objective.

Rust was primarily created to handle CPU-intensive tasks, such as running algorithms and storing large amounts of data. Rust is thus more often used than Golang in tasks that need great performance.

Rust is meant to be a C++ copy. Garbage collection is not a feature in Rust, unlike Go and C++. Instead, Rust uses a borrowed checker to vouch for memory safety. 

To prevent data races, this borrow checker implements data ownership mechanisms. Data race in this context refers to several pointers obtaining the same memory region.

The programming language is one of many that incorporates a lot of little bit of machine programming over an extended period of time. 

Rust implements and encourages a highly concurrent and very safe framework for this kind of programming.

The core components of the Firefox browser now utilize Rust. Rust has been declared the most appreciated programming language since 2016.

Advantages of Rust for Web Development

Now that you have a general understanding of Rust, which accelerates the design process while combining the effectiveness of programming languages such as C++, let’s look at what makes Rust so intriguing:

1. Rust works well with sophisticated programs

Unlike C, Rust provides a single package called Cargo for a variety of functions, including compilation, executing, obtaining libraries, and automatically producing instructions.

According to Rust, “The simplest Rust programs, like the one we’ve written so far, don’t have any dependencies. So if we had built the ‘Hello, world!’ project with Cargo, it would only use the part of Cargo that handles building your code. As you write more complex Rust programs, you’ll add dependencies, and if you start a project using Cargo, adding dependencies will be much easier to do.”

Complex applications run well with Rust when the process consists of several files.

2. It is a high-performance language

Rust is virtually by definition quicker than the typical interpreted language, like Python, since it uses a compiler. Rust is quicker even when compared to programming languages like Java that have a Just-In-Time (JIT) compiler created particularly for improving performance.

3. Rust focuses on safety

Rust takes advantage of a highly stringent compiler that carefully examines every variable to guarantee memory security.

Rust’s Safety – Image Source: Morioh

Segmentation faults, sometimes known as segfaults, don’t exist. Segfaults try to access, read and write to an unauthorized region in memory, which causes applications to crash. 

However, Rust’s ownership mechanism examines the memory used by your program at build time, thereby avoiding these problems.

4. Rust guarantees free abstractions

There are a few traits of Rust that demonstrate the creators had every intention of creating a structured syntax that would improve the user experience.

Rust offers, among other things, free abstractions. Abstractions may be thought of as the additional turns and loops high-level language uses. To be executed, high-level code must be converted into a low-level language or machine code, or both.

Performance is usually somewhat slowed down by these abstractions. However, there is no performance difference between low-level and abstract code in Rust. 

So, performance doesn’t have to be sacrificed in order to use abstractions. They are free of charge.

When Is the Use of Rust Recommended?

Programming languages like Rust are almost universal. However, certain areas are more suitable for it than others.

Systems programming is one area where Rust excels because of its high-quality performance and free abstractions. The process of developing the separate parts of software necessary for the system to operate as a whole is known as systems programming.

The system programmer, according to IBM, installs, modifies, and maintains the operating system as well as installs or updates software used by the system.

It is not unexpected that Rust has certain middle-level features, given that the language draws part of its influence from C++. 

These capabilities or features are capable of handling the degree of complexity needed to manage the memory on the hardware side of things, which is why they are often employed to create computer programs. 

They are nonetheless legible by the human eye, which is uncommon in machine code, despite the absence of abstraction.

Rust is seen as a contemporary language having machine-oriented potential, despite the fact that there can be some disagreement in the tech community over what qualifies as a middle-level language or not.

Rust use cases

• WebAssembly, which lets browsers run efficient code. Additionally, it may be used to create very effective filters in a service mesh like Istio.
• Runtimes for applications. For instance, the developer of Node.js produced Deno, a new JavaScript runtime that is implemented in the Rust programming language.
• CPU-intensive software, including operating systems and games.
• Microservices: REST endpoints and other APIs. Some of the quickest web frameworks, including Actix, are available in Rust.
• Embedded systems, cryptocurrencies and web development are other use cases.

Go vs. Rust: What The Numbers Say?

It is important to note that Go is now quite well-liked among developers. According to the TIOBE Index for August 2022, Go is the 15th most popular programming language, while Rust is placed 20th.

Popular programming languages have some incredible benefits over less well-known languages. Numerous different developers have more in-depth knowledge of them, making it easier to exchange code or assemble a team.

These well-known languages often provide more community support, documentation, and plugins.

Key Takeaways: Go vs. Rust

Golang

If you’re a DevOps team looking to create a scalable, extensible software or system, Go is ideal for designing apps where you’re not only concentrating on security but also on a lot of other characteristics.

Go strives on use and simplicity. It serves a variety of purposes. This is again excellent for DevOps tools and for tiny projects like microservice architecture.

Additionally, the language has a very basic concurrency architecture that makes it extremely easy to develop high-performance programs.

This gives Go a lot of strength and is the reason for its appeal. You can create production-grade microservices in a matter of hours. From CLIs to web apps, Go may be used in a variety of use scenarios.

It is, however, easy to make errors in Golang that have a significant impact on performance. To put it another way, if you don’t start paying attention and know how Golang works, your code won’t run well and might have runtime errors, but with Rust, the compiler forces you to build code that is both fast performing and secure.

Rust

On the other hand, Rust is a bit challenging to learn and operate with and is more geared toward creating apps with a narrow scope where security is the sole thing that matters.

Rust is a systems programming language that focuses on speed, efficiency, and low-level details. Rust intends to completely replace C++ by developing a newer, more straightforward programming language, while Go only adopted parts of the C syntax to build a general-purpose language.

Additionally, Rust’s fantastic build system, as well as zero-cost abstractions feature, enables programmers to write libraries that are simple to use yet very fast for general-purpose tasks like RESTful API, streaming analytics, and much more giving Rust a chance to compete with Golang.

Rust can also be used to create complex systems with thousands and thousands of blocks of code, while Go is often used to create straightforward applications. Additionally, Rust may be utilized in contexts where Go has limited support, such as embedded systems, the edge, or Wasm.

Due to the apparent garbage collector, Rust will perform somewhat better than Go in terms of performance. However, the difference may vary based on the application. The outcomes might vary according to how frequently the GC executes. 

Go vs. Rust: Which One To Pick for Web Development

What option is best for your next task? It comes down to Go vs. Rust. There isn’t just one right response to it, however.

The fact is that based on your requirements and goal, any language may be a good match. Checking the many advantages each language offers and choosing the one that best suits your demands is the most efficient way to assess the language you wish to employ.

Though both Golang and Rust are well-liked, contemporary, and widely-used languages, none is in direct competition with the other.

There are several usage cases for them. Rust outperforms Go in terms of performance for applications that handle enormous amounts of data, but Go’s quick development time makes it a fantastic choice for enterprise-level apps and big development organizations.

Thus the general answer to the Go vs. Rust comparison will be determined based on development and commercial objectives, even if we may go further into both languages and analyze both aspects of it.

Each language has unique benefits and drawbacks as the rivalry goes on. There will be instances in which Golang will perform better and others in which people may choose Rust. Ultimately, you will have to choose the language that best suits your requirements.
