⚖️ Comparison Operators

Last Updated: 11th October 2025

Comparison operators are used to compare two values.
They return a Boolean value — true or false.

Hinglish Tip 🗣: Comparison ka matlab — “Dono values barabar hain ya nahi?”, “badi hai ya chhoti?”. Jaise real life me hum kehte hain - 5 bada hai 3 se → yahi comparison hai.

🗂 List of Comparison Operators

Operator	Name	Example	Result
==	Equal To (checks value only)	5 == "5"	true $\checkmark$ (value same, type ignored)
===	Strict Equal (checks value + type)	5 === "5"	false ✘ (number ≠ string)
!=	Not Equal (value only)	10 != "10"	false
!==	Strict Not Equal (value + type)	10 !== "10"	true
>	Greater Than	8 > 5	true
<	Less Than	3 < 5	true
>=	Greater Than or Equal To	7 >= 7	true
<=	Less Than or Equal To	2 <= 5	true

✏ Mini Example

let x = 10;
let y = "10";
let z = 5;

console.log(x == y); // true (value same)
console.log(x === y); // false (type different)
console.log(x != y); // false
console.log(x !== y); // true
console.log(x > z); // true
console.log(x <= z); // false

⚠️ Important Difference: == vs ===

OperaTor	Checks	Example	Result
==	Only value	5 == "5"	true
===	Value + Type (Strict)	5 === "5"	false

💡 Always prefer === and !== for safer comparisons in JavaScript.

💡 Quick Practice

Compare "10" and 10 using both == and ===.
Check if 15 is greater than or equal to 10.
Verify if "A" is less than "a" (hint: Unicode value compare hota hai).
Compare two Boolean values using !==.
