-**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
-standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
-parser written in ECMAScript (also popularly known as
-[JavaScript](https://en.wikipedia.org/wiki/JavaScript)).
-Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
-with the help of [many contributors](https://github.com/jquery/esprima/contributors).
-
-### Features
-
-- Full support for ECMAScript 2016 ([ECMA-262 7th Edition](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
-- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/es5.md) as standardized by [ESTree project](https://github.com/estree/estree)
-- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
-- Optional tracking of syntax node location (index-based and line-column)
-- [Heavily tested](http://esprima.org/test/ci.html) (~1300 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
-
-### API
-
-Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
-
-A simple example on Node.js REPL:
-
-```javascript
-> var esprima = require('esprima');
-> var program = 'const answer = 42';
-
-> esprima.tokenize(program);
-[ { type: 'Keyword', value: 'const' },
-  { type: 'Identifier', value: 'answer' },
-  { type: 'Punctuator', value: '=' },
-  { type: 'Numeric', value: '42' } ]
-  
-> esprima.parse(program);
-{ type: 'Program',
-  body:
-   [ { type: 'VariableDeclaration',
-       declarations: [Object],
-       kind: 'const' } ],
-  sourceType: 'script' }
-```
