No. This is easily done with 1 line. Maybe a couple extra lines to check inputs.
function findFirstFour(firstFour, wordlist) {
if (typeof firstFour !== 'string' || firstFour.length !== 4) throw new Error('Need 4 characters')
if (!Array.isArray(wordlist) || wordlist.length !== 2048 || wordlist[1353] !== 'powder') throw new Error('Use bip39 English wordlist')
return wordlist.filter(s => s.startsWith(firstFour))[0]
}
