  1. React render is one of the many component lifecycles that a React component goes through. The render method is required whenever you're creating a new React component. React render requires you to return a value. This may either be null, undefined or JSX markup. During this lifecycle you should always keep it pure, and avoid modifying state. Modify state inside the React componentDidMount.
  2. To ensure that each HTML element in the React DOM has a unique identifier, you're required to provide each rendered element with, well, a unique key. You do this by providing a key attribute on the HTML element that you are rendering inside of the Map function. In our example above, we rendered a set of li tags in our Map function

In this document, we'll discuss why render props are useful, and how to write your own. Use Render Props for Cross-Cutting Concerns . Components are the primary unit of code reuse in React, but it's not always obvious how to share the state or behavior that one component encapsulates to other components that need.

We will also learn how to use the useReducer hook for managing state in a React functional component React is a JavaScript library for building user interfaces. React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. In ReactJS whatever we write that looks like HTML is not pure HTML actually. All the HTML looking stuff are JSX, Behind the scene, they are converted to vanilla JavaScript using babel.

Component states are what give React its name. Any time a component's state changes, its render function is called, updating the output. In essence, each component reacts to changes, which is handy for any user interface. Data stored in a state should be information that will be updated by the component's.

This is no new problem nor is it specific to react. It exists in regular HTML + CSS, as well. The only difference is, that we are using a component based approach to create applications/websites.

If React can re-render an input box every time I type a character, and not just generate HTML but also directly manipulate the DOM to reflect it, surely it can generate HTML for the input box upfront.

React Conditional Rendering. In React, we can create multiple components which encapsulate behavior that we need.

5. Comment only where necessary. Attach comments to code only where necessary. This is not only in keeping with React best practices, it also serves two purposes at the same time: It'll keep code visually clutter free. You'll avoid a potential conflict between comment and code, if you happen to alter the code at some later point in.
