how to use the writevsync function from the fs-extra library in typescript

To use the writevSync function from the fs-extra library in TypeScript, we can simply import the writevSync function from the library and invoke it as follows:

index.ts
import { writevSync } from 'fs-extra';

const fileDescriptor = 1; // replace with your file descriptor
const buffers: string[] = ['hello', 'world']; // replace with your list of buffer strings

writevSync(fileDescriptor, buffers); // write buffers to the specified file descriptor

Note that the writevSync function takes in two arguments: the file descriptor and an array of buffer strings to write to the file. You will need to replace the fileDescriptor variable in the example above with the file descriptor of the file you want to write to. And you will also need to replace the buffers variable with your own list of buffer strings that you want to write to the file.
