// Create a function called wisePerson that takes 2 arguments: wiseType and whatToSay.

// This function takes a block of text and presents it as a quote from the wise person. 
// wiseType is the person the quote will be attributed to, and whatToSay is what the wise person will be quoted as saying.

// When called like this: wisePerson('goat', 'Hello world') should return the string 'A wise goat once said: "Hello world".'

const wisePerson = (wiseType, whatToSay) => `A wise ${wiseType} once said: "${whatToSay}"`

// Create a function that takes a single argument: whatToShout.
// The function should return an all-caps version of the string it's 
// given with three exclamation points !!! at the end.

// Given the text shouter('as you can hear i am whispering'), 
// the function should return "AS YOU CAN HEAR I AM WHISPERING!!!".

const whatToShout = str => `${toUpperCase(str)}!!!`

// Create a function called textNormalizer that takes a single argument: text.
// The function should return an all-lowercase string. Any spaces at the beginning
// or end of text should be stripped off.

// When called like this textNormalizer(" let's GO SURFING NOW everyone is learning
// how ") should return the value "let's go surfing now everyone is learning how".

const textNormalizer = text => {
  let arr = text.split(" ").filter( element => element !== "" );
  return arr.join(" ").toLowerCase();
