What is code review?
A code review is the process of examining the written code with the aim of highlighting bugs in order to learn from them.
The code review can be static or dynamic. When code is parsed for errors and syntax errors, this is known as static code checking. When code is executed to compare actual results with expected results, this is known as dynamic code review.
The code can have syntax errors, such as an undefined variable or improper use of keywords, and logical errors if the correct syntax is used but produces incorrect output due to an error in the algorithm. Syntax errors can be removed using a static code check, while logical errors can only be removed using a dynamic code check, since the error in the code is not known to the developer at compile time.
Code reviews are (should) be carried out regularly during the code design phase. An audit meeting is held to determine the reliability of the code and, if possible, propose better alternatives to the existing code. The code is generally checked for security, maintainability, reliability, updatability, flexibility, integrability, and other functions during the code review.
