ast	namedTypes.Program	The script AST
moduleSpecifier	string	The module name to import from (e.g. 'vue')
importName	string	The exported name of the import
localName	string	(Optional) The local alias (defaults to importName)

Example

// import { defineComponent } from 'vue';
createNamedImport(scriptAST, 'vue', 'defineComponent');
