Babel + Typescript in the

Install babel (https://babeljs.io/setup#installation)
Add typescript (https://blogs.msdn.microsoft.com/typescript/2018/08/27/typescript-and-babel-7/)
Change all files from .js extension to .ts.
Set up the development process to be babel-node --extensions '.ts,.tsx’ index.ts
Install tslint. (https://palantir.github.io/tslint/usage/cli/). Here you have a tslint.json file example:

{
 "extends": "tslint:recommended",

$ mkdir myapp
$ cd myapp
$ npm init #follow instructions - wizard app
$ git init
$ npm i express

The easiest way to create a react application is using the create-react-app package. Install it globally in your machine running

$ npm i -g create-react-app

$ mkdir myapp
$ cd myapp
$ npm init #follow instructions - wizard app
$ git init
$ npm i express

	const randomNumber = () => {
	return Math.random();
	}

	// 1. Make it wait for 1 sec. with `setTimeout`
	const timeoutRandomNumber = (cb) => {
	setTimeout(() => {
	cb(null, randomNumber())
	}, 1000);
	}

	// log the `rnd` result in the console using all three async techniques.
	// You can only call console.log inside the `main` function.

	const randomNumber = () => {
	return Math.random();
	}

	// 1. Make it wait for 1 sec. with `setTimeout` and log it on main function
	const timeoutRandomNumber = () => {

	# This file is the main config file for your service.
	# It's very minimal at this point and uses default values.
	# You can always add more config options for more control.
	# We've included some commented out config examples here.
	# Just uncomment any of them to get that config option.
	#
	# For full config options, check the docs:

	// Create a basic animation changing the transform.scale value
	CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];

	// Set the initial and the final values
	[animation setFromValue:[NSNumber numberWithFloat:1.5f]];
	[animation setToValue:[NSNumber numberWithFloat:1.f]];

	// Set duration
	[animation setDuration:0.5f];

	// Add custom timing as a bezier curve
	[animation setTimingFunction:[CAMediaTimingFunction functionWithControlPoints:.34 :.01 :.69 :1.37]];

	// Add a ease in&out timing function on the animation
	[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
