Using Greater Than and Less Than Operators in JavaScript

In this video, I explain how to use the greater than (>) and less than (<) operators in JavaScript. These operators allow you to compare numerical values and write conditional logic based on the results.

Example with Hardcoded Values

if (1 > 0) {
  console.log("Hello world");
}

This logs "Hello world" because 1 is greater than 0.

Using a Variable for Comparison

Let’s make it more dynamic by using a variable:

const fu = 1;

if (fu > 0) {
  console.log("fu is bigger than 0");
} else if (fu < 0) {
  console.log("fu is less than 0");
}

Testing with a Negative Value

Change the value of fu to test the other branch:

const fu = -1;

Now the output will be "fu is less than 0".

Summary

Use > to check if a number is greater than another.
Use < to check if a number is less than another.
Combine these with if, else if, and else for control flow in your programs.

These comparison operators are essential when building logic for games, apps, or any interactive system.
