Use async/await for Asynchronous Code

Tip:

Transition from callback-based code to async/await to make asynchronous code more readable and maintainable.

Example:

javascriptCopy codeconst fs = require('fs').promises;

async function readFile(filePath) {
    try {
        const data = await fs.readFile(filePath, 'utf8');
        return data;
    } catch (err) {
        console.error('Error reading file:', err);
    }
}

Reason: async/await simplifies asynchronous code by avoiding callback hell and making error handling more straightforward.
