Welcome to the fourth Easy JavaScript Tutorial, Beginner JavaScript Tutorial, part of Easy Programming! In this tutorial, we take a look at the various operators available in JavaScript. If you know basic math, this tutorial should be a breeze.
I mainly cover basic operators such as add, subtract, increment, decrement, and multiplication. I briefly covered some comparison operators and will cover them in-depth in a future tutorial when we cover items such as the if statement and loops.
Let's take a brief look at a table showing and explaining the various operators available:
| Operator(s) | Description |
|---|---|
| ++, -- | Increment and Decrement |
| ! | Logical Not |
| *, /, % | Multiplication, Division, and Modulus |
| +, - | Add (concatenate) and Subtract |
| ==, !=, ===, !== | Checks for Equality |
| && | And |
| || | Or |
| =, =+, -=, *=, /=, %= | Assignment operators |
