LeetCode: Group Anagrams Solution

Implementation

1var groupAnagrams = function (strs) {
2  const sortStr = str => str.split("").sort().join("")
3  return [
4    ...strs
5      .reduce((acc, el) => {
6        let sortedStr = sortStr(el)
7        if (!acc.has(sortedStr)) {
8          acc.set(sortedStr, [el])
9        } else {
10          acc.get(sortedStr).push(el)
11        }
12        return acc
13      }, new Map())
14      .values(),
15  ]
16}
