We start off by learning how to use the switch keyword. With the switch keyword, we provide a value, and then the code checks it against different cases. If a case matches the switch condition, it will run the code we provide. We can then use a break to stop our code after that switch statement runs.
But what happens if we don’t provide a break? In that case, the code will keep executing other cases until it runs into a break or reaches the default case. The default case runs if all other cases return false.
Mastering switch cases and the switch keyword is a critical milestone for beginner programmers. It offers a cleaner way to write conditional statements and paves the way for creating more complex programs. Knowing how to use switch cases will impress potential employers and allow you to show off your programming skills to your peers.
However, it’s important to note that understanding switch cases is easier when you already understand how if-else statements work. So make sure to master if-else statements before diving into switch cases.
