Requirements
Basic JavaScript
Description
Dig deep: This course digs deep--you will start by learning the "createElement" function and the virtual node. Once you know what happens under the hood, you can build real confidence and fully utilize the potential of JSX. Keep it short: A short course is easier to finish and more likely to be finished. This also means this course only includes the best and most effective content. Reuse: The examples used in this course are carefully designed so that you can learn multiple topics using just one example. This makes your life easier as you don't have to constantly learn a new project. You can make progress based on existing foundation. Meanwhile, this also gives you the perfect opportunity to review what you have learned. Improve: We'll create a "bad" program first and then show you why it's bad and how to improve it. Understand the problem first: If you don't understand what the problem is, then the solution to that problem can be very difficult to learn. For example, before we learn transition, we'll first learn why transition is needed. Then we'll learn "startTranstion." In the end, we'll learn "useTransition." This helps keep the learning curve smooth. Closure: Closure is the most important JavaScript topic and also the most challenging one. React provides the perfect opportunity to help you understand closure for good! Closure is a double-edged sword. On one hand, it helps us preserve data for future use; on the other hand, closure also means outdated data may be used. useEffect is the perfect example to learn and understand the two sides of closure. "Edgy" Situations: This course has included lots of "edgy" situations that require special treatment. For example, if the state is an array, then useMemo may not work properly. The solution is to add an extra state to control the list order. These edgy situations are very useful in real-life projects and can also help deepen your understanding of React. Visual aids: This course has added lots of animations to show you how React works. These animations will make difficult concepts easier to understand.
