Console.log Quotes

It helps omit uninteresting details, provides convenient building blocks (such as while and console.log), allows you to define your own building blocks (such as sum and range), and makes those blocks easy to compose.

var functionObject = {   greeting: "hello world",   doThings: function() {     console.log(this.greeting);   } } functionObject.doThings();//prints hello world

You can use a similar three-dot notation to call a function with an array of arguments. let numbers = [5, 1, 7]; console.log( max(... numbers)); // → 7 This “spreads” out the array into the function call, passing its elements as separate arguments. It is possible to include an array like that along with other arguments, as in max( 9, ... numbers, 2).

var funcs = []; for (var i = 0; i < 5; i += 1) { var y = i; funcs.push(function () { console.log(y); }) } funcs.forEach(function (func) { func() });
