Javascript Tutorial For Beginners - #3 Javascript Functions Tutorial

This Javascript tutorial covers functions in Javascript. Functions are a great way to store your code in reusable pieces of Javascript code that can be run at any time.

This is a Free Javascript Course designed for beginners. These Javascript lessons cover the basics of Javascript and programming basics from the very beginning.

In the first 2 lessons, we covered variables, several Javascript types, if else statements & comparison operators. Now, we'll cover functions.

Dude, you're awesome! You basically managed to explain 97% of the stuff that my teacher failed to explain in 240 minutes, but you did it in 3 short videos ! I can't wait to watch your other tutorials! THANK YOU!

You have no idea how helpful these tutorials are for complete beginners. Very refreshing, informative, and easy to follow. The first function example was easy, you declare it and you call it, but the returning aspect was a little confusing to me. I had to experiment on my own to kind of get a grasp of what's actually going on when you return, but I think I've got it now. Thanks a bunch!

name and age are not arguments they are parameters. "Will" and "34" are your arguments. Good tutorial though.

I've learnt more from your short videos than the dozens of hour long videos on YouTube. Thank you for your lessons explained clearly.

Hey, as a computer scientist/physicist who just wanted to learn some java script - thank you this series is perfect.

[kasialingat]

I too got confused at this video. The 1st and 2nd we're great. However, you're totally right. I decided to sleep on it and watch it again today and it's making much more sense. Tomorrow I think I'll have it down pat!

I had decided to complete this course in 8 days. .4 videos a week..But m so loving it.. it's just my second day n m almost done with 12 videos.

I not speak English but I fully understand your explanation and speed of content, the best tutorial in three years minimum ..

[UniqueGentlemen]

I am going throught the FCC javaScript certificate and what you provided over tutorial 1-3 has filled so many gaps and allowed me to have fun with understanding!
Thank you!!!

This video was quite clear, not sure why everyone is making a fuss in the comments, there was some stuff to think about but you explained functions way better than anything else I've read online so far. Great stuff, thanks :)

[WIFEYLADIE]

Of all the research I’ve done on understanding Functions, this was the most helpful video I’ve come across so thank you.

[thomrl]

Much simpler and manageable than how codecademy is teaching functions. Thanks for making these videos! :)

I have a couple of years of programming in python for data analysis and machine learning, so programming concepts such as functions, recursion and OOP are familiar to me.

However, when I started to learn about web development, I was quickly overwhelmed by all different technologies that are used to make even a simple website: HTML, CSS, JS, jQuery, Ajax, Flask, Bootstrap and so on. I am not even talking about the server side such as ways to configure them and use with databases. So far I understand what are HTML, CSS. I kind of understand that JS is yet another programming language after watching this video but it is not yet clear how to make it interact with elements on the webpage and why it is so useful in web development.

P.S. I really like the style of teaching of this Youtube channel. Thank you for providing an opportunity to learn!

[Shellybearink]

Omg I love you for making I am learning Web Design right now and my last class threw in random Javascript and I had NO IDEA what anything really did. I sort of got it, but it was confusing.... this helps a LOT! Some functions from the last class are still unclear, but I am hoping that the rest of these videos you have made will make me understand even more! Thank you!

[vicioussilence]

I know another programming language, and this is basically the same thing. There a few differences, but nothing huge! This should be a walk in the park for now.

[davidpinner]

watched this twice as it was so helpful, your teaching style fits perfect with the way i like to learn, easy to follow and just enough information given for you to go away and have a play yourself

[thaygonzalez]

I'm taking clases at a camp, and this is the first time I get how functions work in javascript. Thank you!

[_sandw]

Need to know the basic before watching this video. The video is clear and simple that to understand a little further basics. Thank you for sharing.

[scottbaronxxx]

[bringman]

I was unable to keep up at first as the purpose of the examples was not defined, but I got it at the end! Great video, cheers mate!
