Code review is an important part of the software development lifecycle. It allows developers to improve code quality dramatically.

The process is like writing a book. The writer creates the story, but the editor reviews it, so there aren’t any errors, like confusing “you’re” with “yours”. In this case, code review is the act of reading and evaluating other people’s code. The purpose is to find areas of improvement or bugs at an early stage that might otherwise go unnoticed. The code review processes typically happens before merging with the codebase.

When creating software, it’s important to do code reviews, whether for small or large projects.

Every developer has a unique programming style. If developers continue to use their coding style, this hinders collaboration and delays progress. Code review forces developers to follow specific coding practices. Using this approach, all developers (including new ones) will understand the source code more easily.

Code review is also valuable as team members change throughout a project in the long run. Maintaining a consistent coding pattern will also enable future developers to spend less time analyzing the existing code and instead build new features.

Languages which objective is to translate, map or represent something directly (without a programming logic) are considered coding languages. The most used and known coding languages include:

  • PHP – PHP is a general-purpose scripting language geared towards web development;
  • HTML – defines the meaning and structure of web content;
  • CSS – used to describe a web page’s appearance and presentation;

Coding  require a basic knowledge of programming languages and their syntax as the aim is to write the code that tells the machine to perform a certain task. Programming, on the other hand, requires a much deeper understanding of programming languages, building and working with algorithms, designing web, debugging and testing codes, and project management.

Critical thinking, problem-solving, being analytical-oriented are also essential skills when building complex systems.
