Here’s an overview of the top online programming courses which include Khan Academy, w3schools and Udemy.

This list of no-cost programming courses includes something for everyone, no matter if you’re looking to get into programming for the first time or to see if you enjoy it before you invest in a paid bootcamp or course. Some are introductory, others will help you develop more in-depth knowledge. All require a time commitment, however they are all completely free.

W3schools offers free tutorials for beginners, which teach HTML and CSS. If you have a bit more time, try Udemy’s Tech 101-style course which will cover all the basics to get you started.

Advanced coders will have plenty to select from on Scaler’s Coding course page, which provides numerous online courses for a wide variety of skill levels. They cover everything from data structures to programming languages to give you a good understanding of how to think like an engineer working in software.

And for a more specialized method, you could consider learning programming in Smalltalk, a simplified version of computer language Python that is incredibly easy to learn. In only a few weeks, you’ll be able to master control structures like loops and if statements, while also getting a feel for the language. There is also a more extensive introductory course to guide you through the concepts and language of object-oriented programming.
