The Best Clean Code Linter for Write Clean Code


Clean code is a reader-focused code writing style that produces readable, easy-to-maintain code—writing clean code that doesn’t require much explanation is considered art.

Programmers usually start writing clean code once they realize that the code they are writing is not just for the computer to execute; it’s also for others to read, extend, or build upon.

Thus, writing clean code is a skill every professional programmer should seek to obtain. Of course, it will not be an easy task, but in the end, it is definitely worth the effort.
