nodejs file exists

const fs = require('fs')
// We will convert sync function into a promise function
// so when is ready will provide the result without blocking.
const exists = async (path) => {
	return await new Promise((resolve) => {
		resolve(fs.existsSync(path));
	});
};
// If you have a file name samples on same root it will result true.
exists('./samples.txt').then(res => console.log(res))
console.log(`I'm not blocked as I'll show up on first`)
