What is Switch Statement ?
A switch statement evaluates an expression and executes code based on matching cases. It’s useful when testing a single variable against multiple values.
Syntax:
JavaScript
switch (expression) {
case value1:
// Code to execute if expression === value1
break;
case value2:
// Code to execute if expression === value2
break;
default:
// Code to execute if no cases match
}Example:
JavaScript
let day = "Monday";
switch (day) {
case "Monday":
console.log("Start of the week!");
break;
case "Friday":
console.log("Almost weekend!");
break;
default:
console.log("It's just another day.");
}
