reverse-words-challenge.js

// This problem was asked by Google.
// Given a string of words delimited by spaces, reverse the words in string. For example, given "hello world here", return "here world hello"
// Follow-up: given a mutable string representation, can you perform this operation in-place?

const reverseWords = (str) => str.split(' ').reverse().join(' ')

console.log(reverseWords("hello world here") ===  "here world hello") // true
console.log(reverseWords("hello world here") ===  "hello world here") // false
console.log(reverseWords("who the hell are you") ===  "you are hell the who") // false
