Coding for beginners is all about learning the fundamentals. When you grasp the building blocks of programming, you and the kids you’re teaching become empowered to think like creative coders and build innovative solutions to real-life problems.
Functions in coding are essential – they’re reusable, adaptable, and incredibly useful. Programming functions are like chameleons because they can do just about anything, which means you’re only limited by your imagination.
Let’s explore what functions can do!
What are functions?
Functions are a building block of coding that exist in every programming language. These dynamic pieces of code are really talented – they can do, well, pretty much anything! By telling a computer to perform a specific task, functions drive code forward.
Functions can be small, simple, and straightforward or long, complicated, and multifaceted. They can also hold other functions and various elements of code, such as variables, conditions, and loops.
(P.S. If that sounds like a foreign language to you, we’ve got you covered. Our Camp Coding Camp series covers all of the above and other coding basics for kids.)
Because functions are so flexible and varied, it’s almost impossible to give a nice, neat example that encompasses their full potential. In short, you can create a function that achieves just about anything.
Can you create a function that reminds you to brush your teeth every morning? Definitely! Can you create a function that writes your name backward? Sure. Can you create a function that makes a cartwheeling caterpillar appear on-screen whenever you tap the ‘c’ key? If you have the coding skills, you absolutely can!
Functions can be used and reused
One of the best things about functions is once they exist, you can use them, reuse them, and use them some more. They are the ultimate recycling success story!
Let’s say you’ve programmed a computer game. When the player scores, confetti cover the screen and congratulatory trumpets chime. You give this celebration function a name – maybe ‘CelebrateWin’. Then, every time you want the confetti to rain and trumpets to roar, you can call upon the ‘CelebrateWin’ function. In other words, you don’t have to write out the individual steps over and over again, saving you valuable time.
Functions in coding are adaptable
Just when you thought functions couldn’t get any more useful, here’s another time-saving feature. Functions can be adapted and tweaked to meet your needs.
Here’s an example. Imagine you’re building an online form that asks users to input their name, email address, and phone number. When a user enters their email address, you need the code to make sure it’s valid. So, you create a function that checks whether the user has included an @ character. You also need to check the validity of the phone number. Instead of creating a brand-new function, you adapt your pre-existing function to check that the phone number field contains digits only – no letters allowed.
It sounds kind of complicated – we know! But our function video for kids breaks it down step-by-step. And there are marshmallows involved. And hot dogs. And robots.
What is coding songs for young learners
Functions can do ANYTHING in coding and help you achieve almost ANY specific task. They can also be reused and adapted. If you are ready to teach kids the basics of coding, dive into our Camp Coding Camp series. We cover all the fundamentals of coding – including functions – in a way that’s fun, accessible, and easy to understand.
