JSLint is a "code quality" tool for JavaScript developed by Douglas Crockford, a well-known developer also responsible for JSON, JSMin, ADSafe and parts of YUI. JSLint is parallel to C's lint.

JSLint is a static analysis “code quality” tool for JavaScript developed by Douglas Crockford, a well-known developer also responsible for JSON, JSMin, ADSafe and parts of YUI.

The term “linting” originates from fabric lint-rollers that help remove fluff from clothing. In the same way, a code “linter” helps the developer remove fluff from their code.

The first linting tool was developed for the C programming language when early compilers were not sophisticated enough to identify common programming errors. As the language and compilers matured, so the C linter became redundant and obsolete.

As much of the JavaScript written will not have been near a compiler, the requirement for an equivalent linting tool emerged. This is where JSLint comes in.

A similar tool, exists. It was forked from JSLint.

In the words of its creator:

Warning!

JSLint will hurt your feelings.
