v2.0.0-alpha.1 (#24)

  * **Breaking change**: Requires Node 10.x
  * migrate toolchain: TypeScript, prettier, eslint, jest, rollup
  * export TypeScript types and esm export
  * add support for `Map`, `Set`, negative zero, sparse arrays
  * serialize numeric object keys as numbers (e.g. `{'1':2}` becomes `{1:2}`)

 toSource is a super simple function that converts JavaScript objects back to source code.
 
-Introduction
-------------
+## Introduction
+
 Motivation: JSON doesn't support serializing functions, dates, or regular expressions. I wanted
 a quick and simple way to push trusted data structures with code from Node down to the browser.
 
 This should make it easier to share code and modules between the server and client.
 
-Installation
-------------
+## Installation
 
 ```
 npm install tosource
 ```
 
-Examples

+## Examples
+
 The following code:
 
 ```js
-var toSource = require('tosource')
-console.log(toSource(
-    [ 4, 5, 6, "hello", {
