JavaScript Data Types:
JavaScript variables can hold many data types: numbers, strings, objects and more:

var length = 16; // Number
var lastName = "Johnson"; // String
var x = {firstName:"John", lastName:"Doe"}; // Object

Booleans can only have two values: true or false.

JavaScript objects are written with curly braces {}.

You can use the JavaScript typeof operator to find the type of a JavaScript variable.

An empty string has both a legal value and a type.
