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

Answer 1

Use Array#reduce method.

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

console.log(
  arr.reduce(function(a, b) {
    return a.length <= b.length ? a : b;
  })
)

With ES6 arrow function

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

console.log(
  arr.reduce((a, b) => a.length <= b.length ? a : b)
)
