Find the shortest string in array

Question

How can i find the shortest string in javascript array with different count of array elements? I used

var min = Math.min(arr[0].length,arr[1].length,arr[2]         


        

Answer 1

You could use Math.min with Array#reduce.

var arr = ["aaaa", "aa", "aa", "aaaaa", "a", "aaaaaaaa"];

console.log(
  arr.reduce(function(r, a) {
    return Math.min(r, a.length);
  }, Infinity)
);

ES6

var arr = ["aaaa", "aa", "aa", "aaaaa", "a", "aaaaaaaa"];

console.log(arr.reduce((r, a) => Math.min(r, a.length), Infinity));
