How to check if a string contains all the elements of an array in Javascript

I have a string apple_mango_banana and an array containing [apple,mango].

I want to check if my string contains all of the elements present in the array, if so, I want to show a div with the same ID as my string.

var string="ax_b_c_d";
var array=['b','c','ax','d'];

var arr=string.split("_");

if(array.sort().join("")==arr.sort().join("") && arr.length==array.length)
{
 console.log("match");
 }

Use every() function on the arr and includes() on the str; Every will return true if the passed function is true for all it's items.

var str = 'apple_mango_banana';
var arr = ['apple','banana'];

var isEvery = arr.every(item => str.includes(item));

console.log(isEvery);

You should use Array.every for such cases.

var s = "apple_mango_banana";
var s1 = "apple_mago_banana";
var fruits = ["apple","mango"];

var allAvailable = fruits.every(function(fruit){
  return s.indexOf(fruit)>-1
});

var allAvailable1 = fruits.every(function(fruit){
  return s1.indexOf(fruit)>-1
});

console.log(allAvailable)
console.log(allAvailable1)
