Node.js check if exact filename exists

exists.js

var fs = require('fs');

var path = __dirname;
var filename = 'test.txt';

var files = fs.readdirSync(path);
var exists = files.includes(filename);

// true if file on disk is "test.txt",
// false if file on disk is "TEST.txt"
// fs.existsSync() will return true hence not using
console.log(exists);
