I’m using brilliant and a bit tricky (especially in technical interviews context ) function reduceRight here.

function wordReverser(phrase) {
  const phraseArray = phrase.split(' ');
  const res = phraseArray.reduceRight((acc, curr) => ([...acc, curr]), []);
  return res.join(' ');
}

console.log(wordReverser("Codecademy rules"));

// Leave this so we can test your code:
module.exports = wordReverser;

My go at it:

function wordReverser(phrase) {
** // Write your code here**
** return phrase.split(" “).reverse().join(” ");**
}

console.log(wordReverser(“Codecademy rules”));

// Leave this so we can test your code:
module.exports = wordReverser;

module.exports = wordReverser;

function wordReverser(phrase) {
  const words = phrase.split(" ");
  const reversed = [];
  for (let i = words.length-1; i >= 0; i--){
    reversed.push(words[i])
  }
  return (reversed.join(" "))
}

console.log(wordReverser("Codecademy rules"));

israelz.kollie · November 18, 2021, 3:09pm

My solution:

function wordReverser(phrase) {
  // Write your code here
  let words = phrase.split(" ")
  let reversedWord = words.reverse()

  return reversedWord.join(" ")
}

console.log(wordReverser("Codecademy rules"));

// Leave this so we can test your code:
module.exports = wordReverser;

function wordReverser(phrase) {

I think my solution is a bit long, I kinda went step by step solving using method I know, not trying to optimize.
Just wondering if this kind of approach is still okay, for work interview for example?
Thanks for feedback

function wordReverser(phrase) {
let phraseArray = phrase.split(’ ');
let reverseArray = ;
let finalPhrase = ‘’;
for (let i=phraseArray.length -1; i>=0; i–) {
reverseArray.push(phraseArray[i]);
}
finalPhrase = reverseArray.toString();
return finalPhrase.replace(/,/g, ’ ');
}

console.log(wordReverser(“My name is the John Doe”));

// without using Array.prototype.reverse()

function wordReverser(phrase) {
let prevIdx = 0;
let currentIdx = phrase.indexOf(’ ');
let result = ;

while (currentIdx > -1) {
result.unshift(phrase.slice(prevIdx, currentIdx));
prevIdx = currentIdx + 1;
currentIdx = phrase.indexOf(’ ', prevIdx);
}

result.unshift(phrase.slice(prevIdx, phrase.length + 1))

return result.join(’ ');
}

amrakimmerian · November 26, 2022, 12:39pm

Fastest solution tested:

function wordReverser(str) {
  const words = str.split(" ");
  let result = words[words.length - 1];
  for (let i = words.length - 2; i >= 0; i--) {
    result += " " + words[i];
  }
  return result;
}

function wordReverser(phrase) {
// Write your code here
let reversed = phrase.split(’ ')
let final =
for (let i=reversed.length-1; i>=0; i–) {
final.push(reversed[i])
}

return final.join(’ ')
}

console.log(wordReverser(“Codecademy rules”));

jonathewhale · December 13, 2022, 3:29pm

my solution:

function wordReverser(phrase) {
let array = phrase.split(’ ‘);
array.reverse();
return array.join(’ ');
}

console.log(wordReverser(“Codecademy rules”)) → ‘rules Codecademy’
