Problem 6/30 of LeetCode 30-day challenge

groupAnagrams.js

let groupAnagrams = function(strs) {
  let result = {};
  for(let i = 0; i < strs.length; i++) {
    let word = strs[i];
    // sort the letters, join them together
    let sortedWord = word.split('').sort().join();
    
    if(!result[sortedWord]){
      // if sortedWord is not in object
      // set sorted as key and orig word as array value
      result[sortedWord] = [word];
    } else {
      result[sortedWord].push(word);
    }
  }
  // object.values returns an array (values are arrays)
  return Object.values(result);
};
