AliSawari / promise.js

Created June 4, 2019 13:41

here's how to create promise-based functions

	// say take a number and return its double

	// resolve : the success call . which goes in the first then
	// reject : the error call, which goes in .catch

	function double(number){
	return new Promise((resolve, reject) => {
	if(typeof number == 'number'){
	resolve(number * 2)
	} else reject("the argument should a Number")

AliSawari / then.js

Created June 4, 2019 13:31

the arguments in then calls are the returns of the previous ones

	// with each return , the value goes for the next then in chain
	// you can chain as many thens as you want, even if you dont return a value

	doSomething(args).then(result => {
	return result + 2
	}).then(plusTwo => {
	return plusTwo + 2
	}).then(plusFour => {
	// and the chain continues as many thens as you want...
	}).catch(err => console.log(err))
