What is the syntax of switch case?

Can you explain the syntax of a switch case statement?

Sure! A switch case statement allows you to execute different parts of code based on the value of a variable. Here's a basic syntax:

switch(expression) {
    case value1:
        // code to be executed if expression === value1
        break;
    case value2:
        // code to be executed if expression === value2
        break;
    // you can have any number of case statements
    default:
        // code to be executed if expression doesn't match any case
}

What does the 'break' statement do in a switch case?

The 'break' statement is used to terminate a case in the switch statement. Without it, the code will continue to execute into the next case, which is known as 'fall-through' behavior.

Can you give me an example of a switch case in action?

Absolutely! Here's an example:

let fruit = 'apple';
switch(fruit) {
    case 'banana':
        console.log('Banana is yellow.');
        break;
    case 'apple':
        console.log('Apple is red or green.');
        break;
    default:
        console.log('Unknown fruit.');
}

This will output: 'Apple is red or green.'

Are there any limitations to using switch case?

Yes, switch case statements can only evaluate expressions that return a single value. They also work best with discrete values, like integers or strings, and may not be as flexible as if-else statements for complex conditions.
