Date: 2003oct26 Language: bash Q. javaScript: validate syntax and functionality A. Node.js node.js's check option is a nice way to check the syntax:

node --check myfile.js

But globing (wildcard) doesn't work.

node --check *.js # DOES NOTHING!

So to check all files in a folder do:

find . -name \*.js -exec node --check {} \;

JSHint jshint checks a lot more things. Some of its errors are annoying. You can grep them out or add options to your code to suppress them.

jshint myfile.js

It supports wildcarding:

jshint *.js

but I rarely do this because it produces so many messages. Install with:

npm install -g jshint
