Code reviewing is a practice that deals with finding inefficiencies, bugs, and spots for improvement in a code. It can be considered a skill enhancement practice for employees working in an organization. Code review works by assigning code written by a programmer to a code reviewer to check for any bugs, glitches, and imperfections in the code.

If the code reviewer finds any such problem, it is returned to the programmer for a quick fix. A code reviewer is mostly a more experienced programmer who is well-versed in writing perfect code. Moreover, by doing a code review, the employees can know where they mostly make mistakes or how they can improve their programming skills.
