# JSON Lisp

Execute lisp-like s-expressions written in JSON.

The aim of JSON-Lisp is to allow for an executable code format that is simple and portable, as well as easy to parse and execute in a controlled, sandboxed environment. This allows it to be stored in a database, sent over an HTTP connection, collected from user input, and executed on either a client or a server's machine.

## Installation

Install with npm

    $ npm install --save json-lisp

or yarn

    $ yarn add json-lisp

## Usage

```javascript

const constants = {

  "a": 5,

  "b": 7,

  "+": (a, b) => a + b,

  "-": (a, b) => a - b

};

const jsonLispEnv = new JSONLispEnv(constants);

jsonLispEnv.evaluate(["+", "a", "b"])           //=> 12

jsonLispEnv.evaluate(["-", "a", 3])             //=> 2

jsonLispEnv.evaluate(["+", 2, "b"])             //=> 9

jsonLispEnv.evaluate(["+", "a", ["-", "b", 2]]) //=> 10

jsonLispEnv.evaluateJSON('["+", "a", ["-", "b", 2]]') //=> 10

```
