/**
14
 * Handles default imports from CommonJS modules
15
 * @param {any} obj - Module object to check
16
 * @returns {any} Object with __esModule handling
17
 */
18
function _interop_require_default(obj): any;
19
```
20

21
**Usage Example:**
22

23
```javascript
24
// For: import defaultExport from "commonjs-module";

const defaultExport = _interop_require_default(require("commonjs-module")).default;
26
```
27

28
#### _interop_require_wildcard
29

30
Handles namespace imports from CommonJS modules.
31

32
```javascript { .api }

/**
34
 * Handles namespace imports from CommonJS modules
35
 * @param {any} obj - Module object to convert
36
 * @param {boolean} nodeInterop - Node.js interop mode
37
 * @returns {any} Namespace object
38
 */
39
function _interop_require_wildcard(obj, nodeInterop): any;
40
```
41

42
**Usage Example:**
43

44
```javascript
45
// For: import * as namespace from "commonjs-module";
