JS SWITCH STATEMENT


JavaScript switch Statement

The switch statement is used to perform different actions based on different conditions — like a clean alternative to multiple if-else statements.

🔹 Use Case: Handling menu options, days, grades, status, etc.

📌 Syntax

switch(expression) {
  case value1:
    // code block
    break;
  case value2:
    // code block
    break;
  default:
    // default code block
}

🔍 Example: Detecting the Day

let day = "Wednesday";
switch(day) {
  case "Monday":
    console.log("Start of the week");
    break;
  case "Wednesday":
    console.log("Mid-week check-in");
    break;
  case "Friday":
    console.log("Almost weekend!");
    break;
  default:
    console.log("It's just a regular day");
}
