In this article we will show you how to use the Array.from method in the ECMAscript 6 to create an array from an array-like or iterable object.
The first example will show you how to create an array from a Set which contains the hello world string and a window object and then use the alert method of the window object to show that string on the browser.
var s = new Set(["hello world", window]); var sayHi = Array.from(s); sayHi.alert(sayHi);
The second example will receive a string object and turns it into an array.
var s = "hello world" var sayHi = Array.from(s); alert(sayHi);
Array.from was added to the ECMA-262 standard in the 6th edition which you can now use in the major web browser such as Firefox, Chrome and Opera.
