🔀 Ternary (Conditional) Operator

Last Updated: 11th October 2025

The Ternary Operator is a short way to write if...else conditions in one line.
It checks a condition and returns one of two values based on whether it’s true or false.

Hinglish Tip 🗣: Ye ek shortcut hai “if else” likhne ka — chhoti condition check karke turant result de deta hai.

🧠 Syntax

condition ? value_if_true : value_if_false;

If the condition is true → returns the first value. If false → returns the second value.

⚙️ Example Basic

let age = 18;
let result = age >= 18 ? "You can vote" : "You cannot vote";
console.log(result); // Output: You can vote

⚙️ Example Nested

let marks = 85;
let grade = marks >= 90 ? "A+" : marks >= 75 ? "A" : marks >= 50 ? "B" : "Fail";

console.log(grade); // Output: A

Hinglish Tip 🗣: Nested ternary tab use karo jab multiple conditions ho — jaise grading, status check, etc.Par zyada use mat karo warna code confusing ban jaata hai 😅.

👨‍💻 Quick Practice

  1. Check if a number is even or odd using a ternary operator.
  2. Print "Pass" if marks ≥ 40 else "Fail".
  3. Create a variable isLoggedIn and print "Logout" if true else "Login".
  4. Make a nested ternary for temperature: 30 → "Hot", 15–30 → "Warm", else → "Cold".
