How do I use switch case in JavaScript?

You can use the switch statement to execute different blocks of code based on the value of a variable. Here's a basic example:

Can you show me a code example?

Sure! Here's a simple 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.');
}

What does the break statement do?

The break statement exits the switch block. Without it, the code would continue to execute the next case, which is called 'fall-through'.

Are there any alternatives to switch case?

Yes, you can use if-else statements as an alternative, especially for complex conditions.
