Reactelement vs react.fc

I still recommend simply annotating props instead of using React. But if you do use React. FC in your codebase, there's no reason to remove it.

We don't think of React as shipping its own types. But React's types are a core part of the framework - overseen by the React team, and co-ordinated with React's major releases. In this live coding talk, we'll look at all the types you've been missing out on. How do you get the props type from a component? How do you know what ref a component takes?

React has revolutionized the way we think about web development. As a declarative, efficient, and flexible JavaScript library for building user interfaces, developers can easily create interactive UIs. At the heart of React's design are its fundamental building blocks: React elements, components, and nodes. Understanding these concepts is crucial for developers who aim to master React and build sophisticated applications. React elements are the smallest building blocks of React apps. They describe what you want to see on the screen. In essence, React elements represent a part of the UI. They are immutable and can be nested to describe complex interfaces. On the other hand, React components are the heart of React's composable nature. They encapsulate behavior and rendering logic and can be composed to form complex UIs. Components can be class- or function-based, often called function components FC.

Now we can return whatever we want from it. You typically see it returned from a component's render method or a function component.

Its syntax doesn't exist in JavaScript, so they had to build it into the compiler. They came up with the idea for. But there was an interesting unanswered question: what type should this function infer as? The answer was a special type called JSX. If you hover over a component today, you'll likely see:. JSX is something called a global namespace.

Probably the most common is using the interface already provided by react: FC , which means Functional Component, if the component accept props we only need to add the prop types on it: FC. The other which is implicit by the return type is JSX. Element and widely used as well, and, before React 18, this approach was more reliable. Before React 18 there were a potential issue using FC, it has an implicit children props on it as default, so anyone using a component with the FC type could pass a children on it:. This is the implicit return type if you don't declare it. But let's suppose your component will not always return a valid JSX.

TLDR: No. You should probably not. The consensus in the React community now seems to be that, you should avoid using React.

And I think, based on that, you can stop hating React. Where now it says type children string has no properties in common with type intrinsic attributes. It gives the most flexibility while maintaining the proper type checking. So if you have 17 on React , then Types React is also going to be 17, 18, etc. Let's just render this out. In the App component above, we return a List component that contains several ListItem components. Log in Create account. It represents the object representation of the element you're rendering. For me I just prefer this syntax to this syntax where you add React. Hide child comments as well Confirm. Then we have an input component, which is a react. Both types are the result of React. We've got our also div props from react. ComponentType to handle it. But in terms of actually using this, then actually like assigning types, actually using this within your application code , React.

FC is a type that stands for "Function Component" in React. It is a generic type that allows you to specify the props that a function component will accept. It provides type safety for the props that a component expects to receive.

Its syntax doesn't exist in JavaScript, so they had to build it into the compiler. So what I can do is add something cool and specify that it requires an ID string. This is really cool and makes it just mega flexible. This is perfectly valid JavaScript, but TypeScript would complain because isn't assignable to React. Element and React. They will help you to write clearer, more flexible, and more maintainable components, taking you one step closer to becoming a senior React developer. FC has changed. ReactJS is wildly popular and thus wildly supported. In the first example, MyComponent is strictly defined to return a React element. How do you get the props type from a component? This means that text and number now, this MyNumber component, are both assignable to it.
