Comparing Values

Comparing values is a binary operation. We are comparing the values of the left operand versus the right operand.

JavaScript's Comparison Operators

In JavaScript they are written like this:

• Greater/less than: a > b, a < b.

• Greater/less than or equals: a >= b, a <= b.

• Equals: a == b, please note the double equality sign == means the equality test, while a single one a = b means an assignment.

• Not equals: In math the notation is ≠, but in JavaScript it’s written as a != b.

Examples

// Comparison Examples

let num1 = 42;
let num2 = 6;

console.log(`num1 == num2: ${num1 == num2}`);
console.log(`num1 != num2: ${num1 != num2}`);
console.log(`num1 > num2: ${num1 > num2}`);
console.log(`num1 < num2: ${num1 < num2}`);
console.log(`num1 >= num2: ${num1 >= num2}`);
console.log(`num1 <= num2: ${num1 <= num2}`);

Output:
num1 == num2: false
num1 != num2: true
num1 > num2: true
num1 < num2: false
num1 >= num2: true
num1 <= num2: false

Comparison operation will result into a Boolean value
