+# to-object-reducer
+
+[![Build Status](https://travis-ci.org/olalonde/to-object-reducer.svg?branch=master)](https://travis-ci.org/olalonde/to-object-reducer)
+
+Simple JavaScript/Node.js module which exports a `toObject`
+reducer that can be used with `arr.reduce(toObject)` to convert an array
+`[[key,value],...]` to an object `{ key: value, ... }`.
+
+Example:
+
+```javascript
+[['username', 'olalonde'], ['id',1337]].reduce(toObj, {})
+// => { username: 'olalonde', id: 1337 }
+```
+
+## Install
+
+```sh
+npm install --save to-object-reducer
+```
+
+## Usage
+
+It is meant to facilitate the pattern of converting an object to an
+array of `[key,val]` for easier manipulation with Array methods and back
+to an object, e.g.:
+
+```javascript
+const toObject = require('to-object-reducer')
+
+// Lower case object keys
+const lowerCaseHeaders = (headers = {}) => Object
+  .keys(headers)
+  .map(key => [key, headers[key]])
+  .map([key, val] => [key.toLowerCase(), val])
+  .reduce(toObject, {})
+
+// Or with ES2017 Object.entries
+const lowerCaseHeaders = (headers = {}) => Object
+  .entries(headers)
+  .map([key, val] => [key.toLowerCase(), val])
+  .reduce(toObject, {})
+```
