Did she say hallo.js

// DESCRIPTION:
// You received a whatsup message from an unknown number. Could it be from that girl/boy with a foreign accent you met yesterday evening?

// Write a simple function to check if the string contains the word hallo in different languages.

// These are the languages of the possible people you met the night before:

// hello - english
// ciao - italian
// salut - french
// hallo - german
// hola - spanish
// ahoj - czech republic
// czesc - polish
// Notes

// you can assume the input is a string.
// to keep this a beginner exercise you don't need to check if the greeting is a subset of word (Hallowen can pass the test)
// function should be case insensitive to pass the tests

// My Solution

function validateHello(greetings) {
  greetings = greetings.replace(/[.,!?;:]/g, "");
  arr = ['hello', 'ciao', 'salut', 'hallo', 'hola', 'ahoj', 'czesc']
  let a = greetings.toLowerCase().split(' ')
  let b = a.filter(item => arr.includes(item))
  return !!b.length
}
