JavaScript Learning Path

While a roadmap helps categorize the different concepts you need to learn, it doesn't provide the best learning experience. This is because you often need to jump between concepts in order to internalize the ideas presented and incrementally build the experience.

That is why our courses follow a linear learning path, where each lesson is presented in an order that ensures introducing sub-concepts before we use them in later lessons.
