Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

hasFlags
Check if the current process's arguments contain the specified flags.
Use Array.prototype.every() and Array.prototype.includes() to check if process.argv contains all the specified flags.
Use a regular expression to test if the specified flags are prefixed with - or -- and prefix them accordingly.
const hasFlags = (...flags) =>
flags.every(flag => process.argv.includes(/^-{1,2}/.test(flag) ? flag : '--' + flag));
// node myScript.js -s --test --cool=true
hasFlags('-s'); // true
hasFlags('--test', 'cool=true', '-s'); // true
hasFlags('special'); // false
