How do I use switch statements in programming?

Can you explain how to use switch statements in programming?

Sure! A switch statement allows you to execute different parts of code based on the value of a variable. It's often used as an alternative to multiple if-else statements.

What is the basic syntax of a switch statement?

The basic syntax is:

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

Can you give me an example in JavaScript?

Of course! 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 into the next case, which is called 'fall-through'. This can lead to unexpected behavior.
