Basics

Arrays are container-like values that can hold other values. The values inside an array are called elements.

Instead of writing an if-else on multiple lines, you can use the ternary operator to write the whole statement with one line of code.

Conditional statements control behavior in JavaScript and determine whether or not pieces of code can run.

JavaScript functions are reusable blocks of code that perform a specific task, taking some form of input and returning an output.

Variables are named values and can store any type of JavaScript value.

Operators are the symbols between values that allow different operations like addition, subtraction, multiplication, and more.

A boolean value is one that can either be TRUE or FALSE. If you need to know “yes” or “no” about something, then you would want to use the boolean function.

In JavaScript, Strings are values made up of text and can contain letters, numbers, symbols, punctuation, and even emojis!
