    Esprima can be used to perform lexical analysis (tokenization) or syntactic analysis (parsing) of a JavaScript program.

    A simple example on Node.js REPL:

    > 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.parseScript(program);
    { type: 'Program',
      body:
       [ { type: 'VariableDeclaration',
           declarations: [Object],
           kind: 'const' } ],
      sourceType: 'script' }
