🤔 What is the Ternary Operator?

The ternary operator in JavaScript is a concise way to write an if...else statement. It allows you to perform conditional logic in a single line — perfect for quick, simple decisions. ⚡

📌 Syntax

condition ? expressionIfTrue : expressionIfFalse;

✅ If the condition is true, the expression before the colon (:) executes.
❌ If the condition is false, the expression after the colon executes.

🌐 Basic Example

const age = 20;
const message = age >= 18 ? "✅ You can vote" : "❌ You cannot vote";
console.log(message);

📦 Assigning with Ternary

You can assign values conditionally using the ternary operator — great for inline logic:

const isDarkMode = true;
const theme = isDarkMode ? "dark-theme" : "light-theme";

🧠 Nesting Ternary Operators

Ternary expressions can be nested, but be cautious — they can quickly become unreadable. Use parentheses for clarity.

const score = 85;
const grade = score >= 90 ? "A"
            : score >= 80 ? "B"
            : score >= 70 ? "C"
            : "F";
console.log(grade);
