javascript regular replacement of newlines
Method 1: Use the replace() function
replace The () method is used to replace some characters with other characters in a string, or replace a substring that matches a regular expression.

Method 2: Use replaceAll() function
replaceAll() method is used Replace some characters with other characters in a string, or replace a substring that matches a regular expression. This function will replace all matching substrings.

useState is superior to class components and other state management solutions because it simplifies state management, makes the code clearer, more readable, and is consistent with React's declarative nature. 1) useState allows the state variable to be declared directly in the function component, 2) it remembers the state during re-rendering through the hook mechanism, 3) use useState to utilize React optimizations such as memorization to improve performance, 4) But it should be noted that it can only be called on the top level of the component or in custom hooks, avoiding use in loops, conditions or nested functions.

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.
