JavaScript Hausa #8: Understanding Operators
Hello! Welcome to the eighth lesson in our JavaScript series. Today, we’ll learn about operators—special tools in JavaScript that help you do actions like adding numbers, comparing values, and making decisions. Let’s get started!
What Are Operators?
Operators are like tools in JavaScript that help you work with data. They can add numbers, check if things are equal, or combine conditions. Here are the main types:
- Arithmetic Operators: For math (e.g.,
+,-,*,/). - Comparison Operators: For checking if values are equal or which is bigger/smaller (e.g.,
==,>,<). - Logical Operators: For combining conditions (e.g.,
&&,||,!). - Assignment Operators: For saving values into variables (e.g.,
=,+=,-=).
Examples of Operators
1. Arithmetic Operators:
let num1 = 10; let num2 = 5; console.log(num1 + num2); // Shows 15 console.log(num1 - num2); // Shows 5
2. Comparison Operators:
let age = 20; console.log(age > 18); // Shows true (age is over 18) console.log(age == 20); // Shows true
3. Logical Operators:
let isStudent = true; let hasMoney = false; console.log(isStudent && hasMoney); // Shows false (both must be true) console.log(isStudent || hasMoney); // Shows true (either one is true)
Why Are Operators Important?
Operators are important because:
- They help you do math and comparisons easily.
- They make your code shorter and easier to read.
- They are used in almost every part of programming.
