Comparison operators are used in logical statements to determine equality or difference between variables or values. JavaScript supports several comparison operators, including:

• == (Equal to)
• === (Equal value and equal type)
• != (Not equal)
• !== (Not equal value or not equal type)
• > (Greater than)
• < (Less than)
• >= (Greater than or equal to)
• <= (Less than or equal to)

How to Use Comparison Operators

Here’s a brief explanation of how each operator works:

Equal to (==)

The == operator checks if the values of two operands are equal or not. If they are equal, it returns true.

let x = 5;
console.log(x == 5); // true

Equal Value and Equal Type (===)

The === operator checks if the values of two operands are equal or not, and also checks the types.

let x = 5;
console.log(x === "5"); // false

Not Equal (!=)

The != operator checks if the values of two operands are not equal. If they are not equal, it returns true.

let x = 5;
console.log(x != 4); // true

Not Equal Value or Not Equal Type (!==)

The !== operator checks if the values of two operands are not equal, or if their types are not equal.

let x = 5;
console.log(x !== "5"); // true

Greater Than (>)

The > operator checks if the value of the left operand is greater than the value of the right operand. If it is, it returns true.

let x = 5;
console.log(x > 4); // true

Less Than (<)

The < operator checks if the value of the left operand is less than the value of the right operand. If it is, it returns true.

let x = 5;
console.log(x < 6); // true

Greater Than or Equal To (>=)

The >= operator checks if the value of the left operand is greater than or equal to the value of the right operand. If it is, it returns true.

let x = 5;
console.log(x >= 5); // true

Less Than or Equal To (<=)

The <= operator checks if the value of the left operand is less than or equal to the value of the right operand. If it is, it returns true.

let x = 5;
console.log(x <= 5); // true

Using JavaScript’s comparison operators is fundamental to comparing values in your code. They are essential tools in every developer’s toolkit.
