Summary
In this chapter, we extensively discussed JSX in React. We delved into explaining what JSX is all about as well as the rules guiding the use of JSX in React. Then, we discussed the DOM and how VDOM in React abstracts the native browser DOM for React developers to build a more efficient, cross-browser user interface. JSX improves DOM interaction in React applications and also optimizes the speed for elements in React components to render.
We also examined event handling in React and the use of the SyntheticEvent
event wrapper in React in handling event operations in React. We discussed the subtle differences between JSX and HTML and the rules guiding the usage in React.
Finally, with use cases, we discussed how you can display lists in a React project and how key
and id
are used in managing list items uniquely. We also looked at how you can iterate over objects and display complex nested objects in React.
In the next chapter, we will discuss how to handle form operations...
