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 :).

why do you used the return thing to average? didn’t understand that part, what woudl happen if you just put return?
why does brackets keep giving me error in the words document and console? it says they are not defined
could you say ‘var myResult = average’;
nutshell mean in your video? Nice video and great explanation…………………….
Thanks for the tutorial, this is the best explanation that i found so far. I will definitely recommend you channel
Hi there, thank you for the video upload. May I ask what does “return” do? When is it necessary to include “return”?
Thank you!
why doesnt myresult hv hv dese () in console.log like myresult();
At around three minutes in, could you have the “average” variable as a local variable? Then in the code block, you can just say “average = (a + b) / 2”?
