Help me create a better 2d array, please

My request to the API returns an array of objects. I need to group each item in this array based on the value of one of its keys. Thus, I need to end up with a 2d array of arrays.

Why can't I use a HOC this way?
import React, { Component, PropTypes } from 'react'
export default function onScreen (WrappedComponent) {
return class extends Component {
constructor () {
super()
this.handleScroll = this.handleScroll.bind(this)
this.isRefOnScreen = this.isRefOnScreen.bind(this)
this.state = {
isOnScreen: false

Deploy to `gh-pages` from a `dist` folder on the master branch. Useful for use with [yeoman](http://yeoman.io).

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
