JavaScript 101: Variables, Data Types, and the Foundation of Programming

This class introduces students to JavaScript, the language that powers interactivity on the web.
We begin by answering a simple question: what JavaScript is and what it actually does.

Students will learn:

Why JavaScript exists and where it runs

How JavaScript stores information using variables (let, const, var)

The different data types in JavaScript, grouped into primitive and complex types

How JavaScript “thinks” about numbers, text, and values

Why developers use the terminal and console, and how console.log() helps us see what our code is doing

This class is designed for absolute beginners, with real-life analogies and simple explanations — no prior programming experience required.
