Ranked in these QuestionsQuestion Ranking
Pro Comprehensive material
The lessons and topics are comprehensive and cover the important details of using SQL.
Pro Interactive lessons
There are a series of interactive lessons to learn the basics of SQL, all from within your browser.
Pro Great source from Google search's perspective
Pro Easy to learn
All the tutorials are written in a straightforward and easy to understand way.
Pro Built in editor
Almost every example has a "try it yourself" button which opens up an editor in a new tab. It allows you to play with the example code and see how it works.
Pro Well organized tutorials
All of the lessons are separated into their own pages, which makes it easy to learn about specific concepts.
Con Very few intermediate topics
The tutorial is designed to give beginners an understanding of the basics of SQL. They have started introducing intermediate topics, but currently there is only 3 to choose from.
Con Outdated practices / problem solutions
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.
Con Doesn't care about teaching right
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.
Con Certifications not recognized
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.
Con Written tutorials only
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.
Con It is for profit
What defines what goes is and what gets fixed on w3schools is what gives them profit and what doesn't (through their ads system).
