This change backports changes from the upstream ICU project's maintenance release for ICU 62.2 in order to enable support for the new Japanese Era "Reiwa" in Chromium 69 (which uses ICU version 62.1). Upstream release: http://site.icu-project.org/download/62 Additionally, this change also includes the following fixes/updates: - Update IANA time zone tzdata to 2019a. - Japanese calendar era calculation should use local time, not UTC. - Japanese calendar: use all valid eras for calendar calculations. - Fix LocalMemory move constructor delete issue. This change requires re-generating the checked-in Chromium ICU data files (ex: icudtl.dat) in order for them to have the updated data for the new era name. However, that will be done with a separate commit in order to make the ".patch" files cleaner. Note: All of the checked-in files are be regenerated, even though the Electron project only uses the "common" one. Also included in this change are some minor changes to the scripts used by Chromium for building the data files so that they actually work on Ubuntu.

The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. It is based on Node.js and Chromium and is used by the Atom editor and many other apps.

Installation
To install prebuilt Electron binaries, use npm.
The preferred method is to install Electron as a development dependency in your
app:
npm install electron --save-dev [--save-exact]
The --save-exact flag is recommended for Electron prior to version 2, as it does not follow semantic
versioning. As of version 2.0.0, Electron follows semver, so you don't need --save-exact flag. For info on how to manage Electron versions in your apps, see
Electron versioning.
For more installation options and troubleshooting tips, see installation.
Quick start & Electron Fiddle
Use Electron Fiddle
to build, run, and package small Electron experiments, to see code examples for all of Electron's APIs, and
to try out different versions of Electron. It's designed to make the start of your journey with
Electron easier.
Alternatively, clone and run the electron/electron-quick-start repository to see a minimal Electron app in action:
git clone https://github.com/electron/electron-quick-start
cd electron-quick-start
npm install
npm start

Programmatic usage
Most people use Electron from the command line, but if you require electron inside
your Node app (not your Electron app) it will return the file path to the
binary. Use this to spawn Electron from Node scripts:
const electron = require('electron')
const proc = require('child_process')
// will print something similar to /Users/maf/.../Electron
console.log(electron)
// spawn Electron
const child = proc.spawn(electron)
