/*

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 regex 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

By the way, how cool is the czech republic hallo!!

PS. you can assume the input is a string. PPS. 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)

PS. regex should be case insensitive to pass the tests

*/

function validateHello(greetings) {

let res =/(hello|ciao|salut|hallo|hola|ahoj|czesc)/i.test(greetings)

return res

}
