Arrays Similar.js

/*
Description:
Write a function that determines whether the passed in arrays are similar. Similar means they contain the same elements, and the same number of occurrences of elements.

var arr1 = [1, 2, 2, 3, 4],
    arr2 = [2, 1, 2, 4, 3],
    arr3 = [1, 2, 3, 4],
    arr4 = [1, 2, 3, "4"]

arraysSimilar(arr1, arr2); // Should equal true
arraysSimilar(arr2, arr3); // Should equal false
arraysSimilar(arr3, arr4); // Should equal false
*/
function arraysSimilar(arr1, arr2) {
  arr1=arr1.sort((a,b)=>a-b) 
  arr2=arr2.sort((a,b)=>a-b) 
  return arr1.length>arr2.length?arr1.every((v,i)=>v===arr2[i]):arr2.every((v,i)=>v===arr1[i])
}
