JavaScript 101 – First Programming Steps

This JavaScript tutorial is a subset of lessons from JavaScript Programming for Beginners, which is included as a part of our all-access package.

JavaScript is one of the world’s most important programming languages. Crucial for both web pages and building HTML5 games, the JavaScript programming language is widely used for a variety of purposes – including powering some of NASA’s crucial space missions! Mastering this powerful programming language will not only set you up for success as a developer, but allow you to create robust web applications for both client side and backend interactivity.

Through this JavaScript tutorial, you’ll explore JavaScript basics from the ground-up, learning not only important programming language syntax, but practical application of each coding principle. You’ll also explore how using JavaScript let’s you solve different sorts of problems, which can be used to form the basis of games, websites, mobile apps, Internet of Things apps, and more. Regardless of your coding goals, learning JavaScript programming will provide you an essential skill to your toolkit as you build your first JavaScript programs!

You will learn how to:

  • Store static and dynamic data with variables & arrays
  • Calculate data with common math operators
  • Improve functionality with conditionals and loops
  • Reuse common pieces of code with functions & methods
  • Use object-oriented programming (JavaScript objects, classes, etc.)
  • Explore how JS is used for web pages

… and more!

I love the lectures, concise course objectives, and how they not only teach you enough to get started, but prepare you for the advanced stuff later down the road.



With Zenva, I started learning a more accurate way to approach problems and develop solutions. It’s full of interesting topics that I love to learn in conjunction with my work.



I chose Zenva because of the large selection of topics and the fact that I can choose what courses I want to take whenever I want to take them. That level of freedom is unique to Zenva.



The Unity courses at Zenva helped me achieve a level of comfort with game development that I didn’t think was possible. They give you the confidence to expand your skills, and were so easy to understand.

No prior programming experience is required. We do recommend basic familiarity with HTML.
