How To Create/Use Functions - JavaScript Essentials

Показать описание

Functions are one of the most important things to understand in JavaScript since you will use them everywhere in your code. They are arguably more important than learning how to create a variable since they are that core to how JavaScript works. In this video I will share with you everything you need to know about how to create and use functions in JavaScript.

I've been a software engineer for 10+ years...

I just enjoy seeing how you explain things because it helps me better explain things to non software engineers and my family!

I've been coding for a couple of years and know how it works, yet I still enjoy your videos. One more thing about function, you also can write a default value inside the parameter.

function sum(a = 0, b = 0) {
return a + b;
}

so, it always returns a "value" even though you are not putting any argument

I knew how these worked, but the way you explain things just makes it so much easier to understand.

You explain things so well. Can you make a video for loops and when/how to use the different kinds

Excellent description, presentation and content. Champion! Came looking for a good explanation, because the official linked-in course was quite confusing. Keep up the good work.

Thank you for this! I have struggled to understand JS for so long - HTML and CSS i flew through, but JS I keep getting stumped on. This really cleared a lot of it up. :)
