How does @babel/types.exportDefaultDeclaration work?

@babel/types.exportDefaultDeclaration is a module provided by Babel that allows you to create an AST node representing an export default declaration in a JavaScript module. In detail, this function takes an expression (which is the default export) as an argument and returns an object representing the export default declaration with the given expression as its value. This AST node can then be used to generate JavaScript code using a tool like Babel.
