## Primitive types in JavaScript

JavaScript does have some basic primitive types, but what are they? 

The JavaScript code below outputs the types of four variables with various kinds of values. We'd hope for `string`, `number`, `boolean`, and `date` to be output ... but is this the case? Run the code and find out.

const name = "Bob";
console.log("Type of name:", typeof name);

const age = 30;
console.log("Type of age:", typeof age);

const cool = true;
console.log("Type of cool:", typeof cool);

const dateOfBirth = new Date(1989, 10, 5);
console.log("Type of dateOfBirth:", typeof dateOfBirth);

JavaScript

Nearly! JavaScript does have `string,` `number`, and `boolean` types, but there is no specific `date` type; instead, dates are of type `object`.

Let's play with the other primitive types available in JavaScript which are `bigint`, `null`, `undefined`, and `symbol`. Let's run the code below:

TypeScript adds a rich type system to JavaScript. Before we start to use this rich type system, we need to learn what types we have in JavaScript.
