Switch Statement in JavaScript

The "switch" statement provides a way to execute different blocks of code based on the value of an expression. It offers an alternative to multiple nested "if-else" statements when you have several possible conditions to check.

Syntax:
    switch (expression) {
        case value1:
            // Code to be executed if the expression is equal to value1
            break;
        case value2:
            // Code to be executed if the expression is equal to value2
            break;
            // More cases can be added here
        default:
            // Code to be executed if the expression does not match any of the cases
            break;
    }
