| <p><strong>Esprima</strong> is a high performance, standard-compliant |
| <a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm">ECMAScript</a> parser written in ECMAScript (also popularly known as |
| <a href="http://en.wikipedia.org/wiki/JavaScript">JavaScript</a>).</p> |

| <h4>Features</h4> |
| <ul class="square"> |
| <li>Full support for ECMAScript 5.1 (<a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm">ECMA-262</a>)</li> |
| <li>Sensible <a href="doc/index.html#ast">syntax tree format</a>, compatible with Mozilla <a href="https://developer.mozilla.org/en/SpiderMonkey/Parser_API">Parser AST</a></li> |
| <li>Optional tracking of syntax node location (index-based and line-column)</li> |
| <li>Heavily tested (> 650 <a href="http://esprima.org/test/">tests</a> with <a href="http://esprima.org/test/coverage.html">full code coverage</a>)</li> |
| <li><a href="doc/es6.html">Partial support</a> for ECMAScript 6</li> |

| <p>Esprima serves as an important <strong>building block</strong> for some JavaScript language tools, |
| from <a href="demo/functiontrace.html">code instrumentation</a> to <a href="demo/autocomplete.html">editor autocompletion</a>.</p> |
| <a href="demo/autocomplete.html"><img src="assets/images/autocomplete.png" width="562" height="295" alt="Autocomplete"></a></p> |

| |
| <div class="four columns"> |
| <div class="panel"> |
| <p>Once the full syntax tree is obtained, various <strong>static code analysis</strong> |
| can be applied to give an insight to the code: |
| <a href="demo/parse.html">syntax visualization</a>, |
| <a href="demo/validate.html">code validation</a>, |
| <a href="demo/autocomplete.html">editing autocomplete</a> (with type inferencing) |
| and <a href="demo/index.html">many others</a>.</p> |
| </div> |
| <div class="panel"> |
| <p>Regenerating the code from the syntax tree permits a few different types of <strong>code transformation</strong>, |
| from a simple <a href="demo/rewrite.html">rewriting</a> (with specific formatting) to |
| a more complicated <a href="demo/minify.html">minification</a>.</p> |
| </div> |
| <p>Esprima runs on many popular web browsers, as well as other ECMAScript platforms such as |
| <a href="http://www.mozilla.org/rhino">Rhino</a>, |
| <a href="http://openjdk.java.net/projects/nashorn/">Nashorn</a>, and |
| <a href="https://npmjs.org/package/esprima">Node.js</a>. It is distributed under the |
