How can I check JavaScript code for syntax errors ONLY from the command line?

Question

JavaScript programs can be checked for errors in IDEs or using online web apps but I'm looking for a way to detect syntax errors alone.

I've tried JSLint and JSHint and looked at their options but I haven't been able to find a combination that would exclude warnings and just shows the syntax errors.

How do I check JavaScript code for syntax errors only from the command line?

Answer 1

I use acorn:

$ acorn --silent tests/files/js-error.js; echo $? Unexpected token (1:14) 1  $ acorn --silent tests/files/js-ok.js; echo $? 0 

Install via: npm -g install acorn.
