What you will learn and gain

You will learn how to make your website interactive and dynamic using JavaScript.

What our students are saying

Web design and development is a skill that equips you with the ability to create all kinds of websites or web applications. 

JavaScript is the third programming language you're, most likely, required to learn if you're interested in web development. You should learn it as soon as you finish learning CSS.

Once you're through with HTML, CSS and JavaScript, you would have been equipped with the requisite skill to build the front end part of the website.

You might also require learning JQuery after JavaScript. JQuery makes writing JavaScript super easy.

Note: if you would like to build both the front end and back end of a website by yourself, you will, in addition, need to learn backend programming language like PHP, python, etc.

The nature of our training

Our training is online. We have hundreds of tutorial videos on different web development programming languages uploaded in our website. 

Once you pay and register you will have lifetime access to the course. 

All our paid tutorial videos are downloadable. You can log in anytime and download the tutorial and learn with it.

You also have access to the mentorship of the Admin. You can reach him via WhatsApp on +2348037747461 any time you need his assistance.

This course is designed to be a two weeks course but it allows you to study at your own pace. So, if you're a busy person, you can still cope. 

You can combine the course with other engagements. If you're combining the course with other engagements, however, you might not complete it in two weeks but you will surely complete it eventually.

We encourage our students to dream big and use the skill to power their vision. Most world's richest are programmers. They're rich because they use their skill to power their vision. 

We motivate our students to build applications for themselves as they're learning, by organizing coding and presentation competition among them, once in a while.

If you love to learn how to code professionally, this is a great opportunity for you. We try our best to simplify the courses for easy understanding. 

Even if you know nothing about programming or web development, you will surely find the tutorial very easy.


You need basic knowledge of HTML and CSS before learning JavaScript. If you have no knowledge of HTML and CSS, go through this website and order for them as well.

You also need a Personal computer (laptop or desktop) and knowledge of how to use computer keyboard and mouse.
