edX vs W3Schools

edX does not have the same forum participation from both students and instructors that other websites do, and the form of engagement often does not encourage discussion.

While edX does offer some self-paced courses, you may end up waiting for the course of your choice to be run.

The forums are difficult to sort by date and topic, and are unintuitive to navigate.

The practices that are shown to solve the problems at hand are rarely, if at all, updated. Usually, their tutorials and learning material is updated only after they see their profits drop.

There are multiple errors in the data they show. Although the solutions they show work, they will lead to unmaintainable code. That happens even when the maintainable code alternatives are as easy or accessible to new programmers as the alternatives.

Many professionals in IT agree that w3s certifications are not recognized by them and are deemed useless. Good luck finding any respectable professional that accepts a w3s certification.

What defines what goes is and what gets fixed on w3schools is what gives them profit and what doesn't (through their ads system).

While many learning resources offer a mixture of media in their courses (such as videos, challenges etc.), w3schools offers only written tutorials and code editors. This makes w3schools more beneficial as a quick reference rather than a primary learning resource.
