#2 JavaScript Data Types & Variables(let, var, const) | JavaScript for Beginners Course

Показать описание

A data type is a declaration for variables. This determines the type and size of data associated with variables.

In this video, we will learn about two different types of data: text and numbers which are commonly used in programming. We will first see how we can print these data. Then, we will learn a concept called variables which allows us to store these data and work with them.

Watch the full video to have a clear understanding of the workings of JavaScript variables.

Quiz answer is 1. switchNumber

Also, using ticks instead of quotation marks looks so much easier, at least in JS.

prompt() is no longer working on the online compiler. It throws an error for missing 'readline-sync'. Please, have that fixed.
