Transform ES6 import/export to CommonJS

This feature allows the transformation of ES6 module syntax into CommonJS syntax, enabling compatibility with environments that support CommonJS modules. The code sample demonstrates how an ES6 import statement is transformed into a CommonJS require call.

"use strict";\n\nvar _foo = require("foo");\n\nfunction _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }\n\nvar _foo2 = _interopRequireDefault(_foo);\n\nconsole.log(_foo2.default);

Interoperability with default and named exports

Ensures interoperability between ES6 modules and CommonJS by handling default and named exports. The code sample shows how a default export in ES6 is transformed to be compatible with CommonJS, including the use of Object.defineProperty to simulate ES6 export behavior.

"use strict";\n\nObject.defineProperty(exports, "__esModule", {\n  value: true\n});\nexports.default = void 0;\nvar _default = 'Hello, world!';\nexports.default = _default;
