Any value that you use is of a certain type. In JavaScript, there are the following primitive data types:

Number—this includes floating point numbers as well as integers, for example 1, 100, 3.14.
String—any number of characters, for example "a", "one", "one 2 three".
Boolean—can be either true or false.
Undefined—when you try to access a variable that doesn't exist, you get the special value undefined. The same will happen when you have declared a variable, but not given it a value yet. JavaScript will initialize it behind the scenes, with the value undefined.
Null—this is another special data type that can have only one value, the null value. It means no value, an empty value, nothing. The difference with undefined is that if a variable has a value null, it is still defined, it only happens that its value is nothing. You'll see some examples shortly.
Any value that doesn't belong to one of the five primitive types listed above is an object. Even null is considered an object, which is a little awkward—having an object (something) that is actually nothing. The data types in JavaScript the data types are either:

Primitive (the five types listed above), or
Non-primitive (objects)
