JavaScript Switch Cases, The Switch Keyword in JavaScript, Codecademy Programming Full Course 2023

Learn about JavaScript Switch Cases, using The Switch Keyword in JavaScript. A Codecademy Programming Full Course 2023, In this lesson we take a look at a shorter and cleaner way to do conditionals instead of if-else statements, called a switch statement. With a switch statement we get the same functionality as an if-else statement with less code and cleaner looks. We are able to use the switch keyword to provide a value to it and then it will check it against different cases. The case that matches the switch condition will run the code we provide. We are then able to use a break to stop our code after that switch statement runs. We learn that if we do not provide a break, then the code will keep executing other cases until it runs into a break, or all the way down to the default case. The default case will run if all other cases return false. Understanding switch cases is important and is easy when you already understand how if-else statements work. Mastering switch cases and the switch keyword is an epic milestone for beginner programmers and pave the way for creating fancy programs. Learn the switch case to impress potential employers and to show off to your other programming friends. Continue on once you have mastered the switch case in JavaScript programming. JavaScript Switch Cases are awesome to understand and may come in handy in the future.

If you’re learning JavaScript programming, you may have heard of switch cases and the switch keyword. But what are they, and why are they important?

In this Codecademy Programming Full Course 2023, we dive deep into switch cases and learn how to use the switch keyword in JavaScript. Switch cases are a shorter and cleaner way to do conditionals, compared to if-else statements. They offer the same functionality as an if-else statement, but with less code and a cleaner look.

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.

In summary, JavaScript switch cases and the switch keyword provide a cleaner and more efficient way to write conditional statements. It’s a must-learn skill for beginner programmers and a valuable asset to have in your programming toolkit. Start by understanding how the switch keyword works and then dive deeper into the world of switch cases. With practice and patience, you’ll soon be creating impressive programs with ease.
