During a university lecture, I accidentally came across the introduction of W3Schools, a free learning platform. It serves as an excellent bridge for beginners to start learning a new language or tool from scratch. Moreover, it allows users to search for specific keywords or functions related to each programming language. In addition to foundational programming languages, W3Schools provides basic knowledge of popular topics like Artificial Intelligence, Machine Learning, web front-end frameworks, back-end database creation, and more.
The platform offers 7 main categories, with a total of 68 related or standalone courses and nearly 40 references available for consultation.
Taking Java as an example for this learning objective, the courses usually begin with basic syntax, gradually increasing in difficulty with topics such as loops and functions. Eventually, it transitions into object-oriented concepts, breaking down key ideas into individual chapters, such as Encapsulation, Inheritance, and Abstraction.
Throughout the learning process, W3Schools provides many code examples to help users understand concepts better. Users can also experiment with the built-in editor by modifying the code and testing their understanding with different logic. After completing each chapter, there are small exercises to help learners promptly assess their progress (often focused on syntax learning).
It's worth mentioning that upon completing a course, users can apply for a certificate from W3Schools through an exam and other verification processes (at an additional cost). This certificate represents a foundational understanding of the course content, making it highly recommended for beginners seeking to continually enhance their skills.
