Arrays as objects in JavaScript

Arrays are actually a special case of objects. This can be verified by checking the array through the operator typeof:

console.log(typeof []); // shows 'object'

Without running the code, determine what will be output to the console:

console.log( typeof {x: 1, y: 2, z: 3} );

Without running the code, determine what will be output to the console:

console.log( typeof [1, 2, 3] );

Without running the code, determine what will be output to the console:

let arr = [1, 2, 3]; console.log( typeof arr );

Without running the code, determine what will be output to the console:

let arr = [1, 2, 3]; console.log( typeof arr[0] );

Without running the code, determine what will be output to the console:

let arr = ['1', '2', '3']; console.log( typeof arr[0] );
