// WHAT IS A SWITCH STATEMENT?

// SWITCH SYNTAX

// switch (expression) {

// case value1:

// // code to execute

// break;

// case value2:

// // code to execute

// break;

// default:

// // code to execute if no case matches

// }

// EXAMPLE

// let day = "Monday";

// switch (day) {

// case "Monday":

// console.log("Start of the work week. Let's be productive!");

// break;

// case "Tuesday":

// console.log("Keep the momentum going!");

// break;

// case "Wednesday":

// console.log("Midweek checkpoint. You're halfway there!");

// break;

// case "Thursday":

// console.log("Almost Friday. Stay focused!");

// break;

// case "Friday":

// console.log("Last push before the weekend!");

// break;

// case "Saturday":

// case "Sunday":

// console.log("Enjoy your weekend!");

// break;

// default:

// console.log("That's not a valid day.");

// }

// THE IMPORTANCE OF BREAK

// let score = "B";

// switch (score) {

// case "A":

// console.log("Excellent!");

// case "B":

// console.log("Good job!");

// case "C":

// console.log("You passed!");

// case "D":

// console.log("You need improvement.");

// default:

// console.log("Invalid grade.");

// }

// SWITCH VS IF-ELSE

// With if-else:

// let fruit = "apple";

// if (fruit === "apple") {

// console.log("Apples are $2 per pound");

// } else if (fruit === "banana") {

// console.log("Bananas are $1 per pound");

// } else if (fruit === "orange") {

// console.log("Oranges are $3 per pound");

// } else if (fruit === "grape") {

// console.log("Grapes are $4 per pound");

// } else {

// console.log("Fruit not available");

// }

// With switch:

// let fruit = "apple";

// switch (fruit) {

// case "apple":

// console.log("Apples are $2 per pound");

// break;

// case "banana":

// console.log("Bananas are $1 per pound");

// break;

// case "orange":

// console.log("Oranges are $3 per pound");

// break;

// case "grape":

// console.log("Grapes are $4 per pound");

// break;

// default:

// console.log("Fruit not available");

// }

// PRACTICAL EXAMPLE

// let operation = "+";

// let num1 = 10;

// let num2 = 5;

// let result;

// switch (operation) {

// case "+":

// result = num1 + num2;

// console.log(`${num1} + ${num2} = ${result}`);

// break;

// case "-":

// result = num1 - num2;

// console.log(`${num1} - ${num2} = ${result}`);

// break;

// case "*":

// result = num1 * num2;

// console.log(`${num1} * ${num2} = ${result}`);

// break;

// case "/":

// if (num2 !== 0) {

// result = num1 / num2;

// console.log(`${num1} / ${num2} = ${result}`);

// } else {

// console.log("Cannot divide by zero!");

// }

// break;

// default:

// console.log("Invalid operation. Use +, -, *, or /");

// }

// SWITCH WITH EXPRESSIONS

// let age = 25;

// switch (true) {

// case age < 13:

// console.log("You're a child");

// break;

// case age < 20:

// console.log("You're a teenager");

// break;

// case age < 60:

// console.log("You're an adult");

// break;

// default:

// console.log("You're a senior");

// }

// COMMON MISTAKES

// Mistake 1: Forgetting break

// Mistake 2: Using non-strict comparison

let x = "1";

switch (x) {

case 1: // won't match because "1" !== 1

console.log("Matched");

}

// Mistake 3: Forgetting default
