Percent Encoding

const urlEncode = function(text) {
  //removes the outer empty spaces
  let newText = text.trim().split('');
  let textSize = text.length;
  //check through the rest of the string
  for (i = 0; i < textSize; i++){
    if (newText[i] === ' '){
      newText[i] = '%20';
    }
  }
  return newText.join('');
};
