Which are in?

Description

Given two arrays of strings a1 and a2 return a sorted array r in lexicographical order of the strings of a1 which are substrings of strings of a2.
Example 1:
a1 = ["arp", "live", "strong"]
a2 = ["lively", "alive", "harp", "sharp", "armstrong"]
returns ["arp", "live", "strong"]
Example 2:
a1 = ["tarp", "mice", "bull"]
a2 = ["lively", "alive", "harp", "sharp", "armstrong"]
returns []
Notes:
Arrays are written in "general" notation. See "Your Test Cases" for examples in your language.
In Shell bash a1 and a2 are strings. The return is a string where words are separated by commas.
Beware: r must be without duplicates.

My answer

function inArray(array1,array2){
  let result = [];
  
  for(let i = 0; i < array1.length; i++) {
    for(let j = 0; j < array2.length; j++) {
      if (array2[j].includes(array1[i])) {
        result.push(array1[i])
      }
    }
  }
  
  return [...new Set(result)].sort()
}

Other solutions

function inArray(arr1, arr2) {
  return arr1.filter(function(needle) {
    return arr2.some(function(haystack) {
      return haystack.indexOf(needle) > -1;
    });
  }).sort();
}

function inArray(array1,array2){
  return array1
    .filter(a1 => array2.find(a2 => a2.match(a1)))
    .sort()
}
