* Comparison using is when operands support __eq__ Comparison using 'is' when equivalence is not the same as identity When you compare two values using the is or is not operator, it is the object identities of the two values that is tested rather than their equality. If the class of either of the values in the comparison redefines equality then the is operator may return False even though the objects compare as equal. Equality is defined by the __eq__ or, in Python2, __cmp__ method. To compare two objects for equality, use the == or != operator instead. Recommendation When you want to compare the value of two literals, use the comparison operator == or != in place of is or is not. If the uniqueness property or performance are important then use an object that does not redefine equality. * fix: Comparison using is when operands support __eq__ Comparison using 'is' when equivalence is not the same as identity When you compare two values using the is or is not operator, it is the object identities of the two values that is tested rather than their equality.

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)
