React Native Export Default - Javascript

When building a React Native application, we often need to export components or functions to be used in other parts of the application. This is where the export default keyword comes in.

The export default keyword is used to export a single value or function from a module. This value or function can then be imported into other parts of the application using the import keyword.

Here's an example of how to use export default to export a function in a React Native component:

export default function MyComponent(props) {
  // component code here
}

In this example, we are exporting a function called MyComponent using the export default keyword. This function takes in a single parameter called props and returns the component code.

To import this component into another part of the application, we can use the following code:

import MyComponent from './MyComponent';

In this code, we are importing the MyComponent function from the MyComponent module using the import keyword.

One important thing to note is that when importing a default export, the name of the imported value must match the name of the exported value. This is why we are using the same name (MyComponent) in both the export and import statements.

In conclusion, the export default keyword is an essential part of building React Native applications. It allows us to easily export values and functions from modules and use them in other parts of the application.
