Bug

In simpler terms, a bug could mean late loading of pages, unworking a button, or different instances altogether. Bugs can affect a website in a minor way,from slowing down the working of a website to the breaking down of the website completely, resulting in a major issue. Hence, flaws are to be fixed with checking the codes. The bugs are mainly caused by the following:-
Programming errors are a result of the improper functioning of a website or incorrect display of content. These errors could be categorised as syntax, logic or run-time errors
Design Flaws stem from the initial insufficient design of a website.
Compatibility issues arising from the malfunctioning of the website in several browsers.
Integration issues occur due to the failure of different systems that work together within a website.

Managing bugs is significant for building the users’ trust and satisfaction during website development. They are tackled through testing, user feedback and error reporting tools. The process includes reproducing the bug, and identifying the cause of a bug. Then, the code is fixed and verified to use the corrected code on to live site.
