I am trying to get all anagrams from a array of words:

arr = ['cab','bac','tru']

The expected output is supposed to be:

{abc: ['cab','bac']}

I tried to implement the below code:

var words = ['cab', 'bac', 'mihir']
let result = {}

words.forEach(word => {
  var a = word.split("").sort().join("");
  result[word] = a

})

console.log(result)

How do I iterate over the values so that I can access the keys if they have the same values?

CodePudding user response：

You can use the sorted words as keys in an object, and collect each word that matches the key in an array:

var words = ['cab', 'bac', 'mihir']
let result = {}

for (const word of words) {
  const sorted = word.split("").sort().join("");

  if (sorted in result) {
    // If there is already an entry in the result, append this word
    result[sorted].push(word);
  } else {
    // Otherwise, create one
    result[sorted] = [word];
  }
}

console.log(result);
