Arrays are objects js-internally

by web5me August 19, 2015

JavaScript

// create an array
var a = ['☯']; // a[0] = '☯'
// 'add' a property to the array object (using an identifier)
a["0"] = ' ❤';

// JS arrays are actually objects internally
document.write( a[0] === a["0"] ); // -> true
// a[0] is now ' ❤';
document.write( a[0] ); // -> ' ❤'
