how to use the pathexists function from fs-extra in javascript

To use the pathExists function from the fs-extra module in node.js, you will first need to install the module by running npm install fs-extra in your terminal.

Here's an example of how to use pathExists function:

index.tsx
const fs = require("fs-extra");

async function checkIfFileExists(filePath) {
  try {
    const exists = await fs.pathExists(filePath);
    console.log(`The file ${filePath} ${exists ? 'exists' : 'does not exist'}.`);
  } catch (err) {
    console.error(err);
  }
}

checkIfFileExists("/path/to/your/file");

This example shows an asynchronous function checkIfFileExists that accepts a filePath argument. Within this function, the pathExists function is called using await to check whether the file at the specified filePath exists or not. If the file exists, it logs the message "The file [filePath] exists." to the console, and if it does not exist, it logs "The file [filePath] does not exist." to the console. If there is an error during the process, the error is logged to the console.

Note that pathExists is an asynchronous function so you need to call it using an await keyword. Also, to use async/await the function should be declared as async.
