How does @babel/types.importDefaultSpecifier work?
The @babel/types.importDefaultSpecifier is a function provided by the Babel library that represents a default import specifier in an abstract syntax tree (AST) node. An import default specifier is used to import the default export from a module, and can be used in the import statement in JavaScript/TypeScript code. When creating an AST node using Babel, importDefaultSpecifier can be used to create a new node representing a default import specifier. The function takes in an object with the following properties: local: The local name of the default import specifier. imported: The imported name of the default import specifier (which will be the string "default"). The returned node is an instance of the ImportDefaultSpecifier class in the Babel AST, and can be used in constructing a larger AST representing the imported module. Overall, @babel/types.importDefaultSpecifier provides a way to create an AST node representing a default import specifier in JavaScript/TypeScript code, which can be useful in cases where you need to programmatically generate code or perform transformations on an existing AST.

const t = require("@babel/types"); const specifier = t.importDefaultSpecifier(t.identifier("myModule")); console.log(specifier);
In this example, we use @babel/types.importDefaultSpecifier to create a new AST node representing a default import specifier. We first import the @babel/types library and assign it to the variable t. We then call the importDefaultSpecifier function provided by t, passing in an object with a local property set to an identifier node with the value 'myModule'. This creates a new instance of the ImportDefaultSpecifier class in the Babel AST, which represents a default import specifier with a local name of myModule. We log the resulting node to the console to show its structure and properties. Note that in order to use @babel/types.importDefaultSpecifier, you need to have the Babel library installed and imported in your application.
