Export Default also creates a fallback value which means that if you try to import a function, class, or object which is not present in named exports.

The export statement is used when creating JavaScript modules to export objects, functions, variables from the module so they can be used by other programs with the help of the import statements. There are two types of exports. One is Named Exports and other is Default Exports.

Exports without a default tag are Named exports. Exports with the default tag are Default exports. Using one over the other can have effects on your code readability, file structure, and component organization. Named and Default exports are not React-centric ideas.

Default exports enable developers to export only a single class, function, variable, object, array, constant, etc. You write module. exports and assign a component that you want to export as default exports. Note: If you are interested in learning what is named exports in Node.

So, when you're exporting only one element from your module and you don't care of its name, use export default .
If you want to export some specific element from your module and you do care of their names, use export const.
