        Installation

        ~~~~~~~~~~~~

        .. code:: shell

            pip install 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:

        .. code:: javascript

            >>> import esprima

            >>> 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)

                body: [

                        kind: "const",

                        declarations: [

                                init: {

                                    raw: "42",

                                    type: "Literal",

                                    value: 42

},

                                type: "VariableDeclarator",

                                id: {

                                    type: "Identifier",

                                    name: "answer"

],

                        type: "VariableDeclaration"

],

                type: "Program",
