Course Description

The best way  for a  beginner to enhance their skills is by practicing building various projects.

This course is a beginner course for those who have some basic knowledge of how HTML, CSS and JavaScript works. 

Some of the projects you will be creating in this practical hands on course include:

  • Creating a functional calculator
  • Creating a digital clock
  • Creating  a word count tool
  • Creating a button color changer
  • Creating a percentage tip calculator
  • Creating a contact form with local storage

HTML will be used to create the structure of these applications.

CSS will be used to apply styling to make the applications look nice and presentable.
Java script creates the functionality for the app and required HTML and CSS to be in place before it can do it's thing.
They are are like a canvas for JavaScript to work on.

In this course you will learn useful and practical steps to creating web based browser apps that will work when viewed with any modern web browser.
I will be using google chrome for this project and i advise you do the same.

A good text editor makes writing code fun and productive. 
 I will be using sublime text editor for this course. It is a cross platform text editor that will work on any platform  like windows and macs.It is free to download and use but recommend that you purchase a full license after trying it out if you enjoy using it.
Another good cross platform text editor is brackets which is open source and completely free to use. By open source i mean  developers from around the world can contribute to make it even better.

By the end of this course you will be confident to build more useful projects .

loading the code and then explaining what each part is doing works perfectly instead of explaining each part step by step.

By Fero Hriadel on 4/1/2020

Half-way thru the course. The guy takes it really slow to explain things so even a dummy like myself can follow. Very simple projects - just what I needed. Great beginners' practice.

By Rohan Ghogare on 3/14/2020

Hello Overall structure of course is well arranged, but some more complexity can be added which can help intermediate level people to enhance their skills.

By Laura C. Hellings on 5/5/2019

It's amazing to create the projects with the videos and troubleshoot as I go. Seeing a final working piece that can be built on later is really exciting!

By James Liverman on 3/1/2019

Very good on the html, css portions. Could have explained the calling of the javascript function a bit better ie OnClick="calc.display.value+='0'" but breaks down the steps very well.

By Ebuka Gerard Nwabueze on 11/26/2018

It has been amazing because, it's concise and straight to the point.

By John Zhao on 8/15/2018

Very basic but useful tutorials. Each section is very clear and straightforward. However, certain knowledge lacks of in-depth explanation and there are way too much duplicate information.

By David Stout on 2/4/2018

Lots of quick little victories (program ran as expected) to give me confidence to learn JavaScript.

By Wouter Den Dulk on 11/18/2017

Exactly what I was looking for. How to make things. Thankyou for showing me how. Wederik the Netherlands

By Pietro Scagliarini on 4/25/2017

CI sono diversi bug nel codice (errori evidenti di distrazione) e per una persona che sta iniziando ad imparare è un po' deludente vedere che le cose non funzionano, oltre a perdere e non capire dei pezzi importanti. Se sistemano un po' di punti, la valutazione può migliorare. Gli ultimi progetti sono poco impiegabili e troppo semplici rispetto ad altri (sembrano buttati lì di fretta). Quello sui feed Google impraticabile
