Arrays

Back to:

Organising and storing data is a foundational concept of programming.

One way we organise data in real life is by making lists. Let’s make one here:

New Year's Resolutions:

1. Keep a journal 
2. Take a falconry class
3. Learn to juggle

Let’s now write this list in JavaScript, as an array:

let newYearsResolutions = ['Keep a journal', 'Take a falconry class', 'Learn to juggle'];

Arrays are JavaScript’s way of making lists. Arrays can store any data types (including strings, numbers, and booleans). Like lists, arrays are ordered, meaning each item has a numbered position.

Here’s an array of the concepts we’ll cover:
