Problem to solve is to capitlize the first letter of each word in a string using '.split' '.map' and 'join'. Currently implemented split and map to get the word capitlised and rejoined it, but confused as to where I need to put the .join.
Expected: "The Lord Of The Rings"
Received: ["The", "Lord", "Of", "The", "Rings"]
function titleCase(string) {
return string.split(' ').map(word => word.charAt(0).toUpperCase() + word.substr(1))
}First: split the string
Second: Capitalize word
Third: Join words
return string.split(' ').map(word => word.charAt(0).toUpperCase() + word.substr(1)).join(' ');
