Data Types
Lab: Introduction to jQuery and JavaScript
Video Runtime: 15:44
Let’s do a quick review of data types in JavaScript. We’ll talk about primitive types (string, number, boolean, undefined, and null) as well as objects and arrays.
You will learn:
- JavaScript is a loosely typed (dynamic) language, meaning the data type is assigned by its value
- Changing data types
- Checking what the data type is with
typeof - Arrays and Objects
For a more in-depth lesson on data types, make sure you sign up for JavaScript for WordPress and/or MDN JavaScript data types and data structures.
There’s a time to code and …. yup, that sums it up.
