JSHint is a fork of Douglas Crockford’s JSLint that is designed to be more flexible than the original. Our goal is to make a tool that helps you to find errors in your JavaScript code and to enforce your favorite coding style.
We realize that people use different styles and conventions, and we want our tool to adjust to them. JSHint will never enforce one particular convention.
