+- Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](http://esprima.org/doc/index.html#ast) compatible with Mozilla
+[Parser AST](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
- Optional tracking of syntax node location (index-based and line-column)
-- Heavily tested (~1200 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
+- Heavily tested (> 650 [unit tests](http://esprima.org/test/) with [full code coverage](http://esprima.org/test/coverage.html))
+- [Partial support](http://esprima.org/doc/es6.html) for ECMAScript 6
