JavaScript Switch Statements: A Complete Guide

The switch statement is used to execute one block of code among many options. It evaluates an expression, matches the result to a case, and executes the associated block.

Syntax:

switch (expression) { 
  case value1: 
    // Code to execute if expression === value1 
    break; 
  case value2: 
    // Code to execute if expression === value2 
    break; 
  // Add more cases as needed 
  default: 
    // Code to execute if no case matches 
}

Example

let day = 3;

switch (day) {

case 1:

console.log("Monday");

break;

case 2:

console.log("Tuesday");

break;

case 3:

console.log("Wednesday");

break;

case 4:

console.log("Thursday");

break;

case 5:

console.log("Friday");

break;

default:

console.log("Weekend");

}
