To use the hasOwnProperty function from the fs-extra library in TypeScript, you can follow the below steps:

2. Import the fs-extra module at the beginning of your TypeScript file.

index.ts
import fs from 'fs-extra';
27 chars
2 lines

3. Use the hasOwnProperty function from the fs-extra module as shown below:

index.ts
const fileStats = await fs.stat('/path/to/file');

if (fileStats.hasOwnProperty('size')) {
  console.log('File size:', fileStats.size);
}

The hasOwnProperty function can be used to check if a specific property exists in the returned object of a fs method like fs.stat. In the above example, we are checking if the size property exists in the returned object of fs.stat before logging the value to the console.

Note: It is important to use await when calling asynchronous fs methods to make sure the call completes before checking the object properties.
