The copySync function takes two arguments:

• The source file or directory path.
• The destination file or directory path.

Note that the copySync function will overwrite the destination file or directory if it already exists.

Here's an example of how you can use the copySync function in TypeScript:

index.ts
import * as fsExtra from 'fs-extra';

try {
    fsExtra.copySync('src/file.txt', 'dest/file.txt');
    console.log('Successfully copied file.txt');
} catch (err) {
    console.error(`Failed to copy file.txt: ${err}`);
}
