Hey class, so in this JavaScript tutorial I want to introduce you to the world of functions. Yep, I think you’re ready for them :). Functions allow you to chunk parts of code together into logical sections, and call that code at any time. For example, you may have a function to cycle through all of your images on a web page, and implement a zoom functionality on the. You’d probably call this function something like imageZoom.
So, functions are a really cool and integral part of JavaScript, and something you should try and get into the habit of using early on in your JavaScript development, so that your code is always readable and tidy for yourself and other developers.
At first, functions in JavaScript can be a tricky concept, so by all means fire away with any questions you have down below :).
