What is React.FC Type?

Last updated on 16 Feb, 2023

If we are using TypeScript along with React, we might use React.FC type. FC stands for function component.

If we write a function that returns a React component, we can use this type.

const App: React.FC = () => {
  return <div>Hello</div>;

If the function does not return a React component, TypeScript will throw an error. Here is a function that will throw an error:

const App: React.FC = () => {
  return "hello";

The error message will be:

Type 'string' is not assignable to type 'ReactElement<any, any>'

React.FC is the short version of React.FunctionComponent. We can use any type according to our convienience.
