How does a switch case work in programming?

How does a switch case work in programming?

A switch case is a control statement that allows a variable to be tested for equality against a list of values. Each value is called a case.

Can you give me an example in JavaScript?

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 happens if I forget the break statement?

If you forget the break statement, the code will continue to execute the next case(s) until it hits a break or the end of the switch.

Are there any alternatives to switch case?

Yes, you can use if-else statements as an alternative to switch case for handling multiple conditions.
