##JShint JSHint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules. It was forked from Douglas Crockford's JSLint project, as it was felt that the original did not allow enough customization options.

###JShint vs. JSlint
If you're looking for a very high standard for yourself or team, JSLint. But its not necessarily THE standard, just A standard, some of which comes to us dogmatically from a javascript god named Doug Crockford. If you want to be a bit more flexible, or have some old pros on your team that don't buy into JSLint's opinions, or are going back and forth between JS and other C-family languages on a regular basis, try JSHint
