How do i find if an array value is in a string and remove it?

Question

I want something like this:

var string = "apple banana";
var array = ["apple", "banana", "orange", "grape"];
for(var i=0;i<array.length;i++){
  if(array[i] is found in (string) {
    remove the value;
  }
}

something like that. so basically, it would:

Declare a string and an array
Iterate through the array
If the array[i] value is present exactly in the string, it would remove it
The iteration should continue as normal

In case it still doesnt make sense:

String is "1 3 b c"

Array contains "1", "2","3", "a", "b", "c"

The array should now only contain "2" and "a".

.filter the array by whether the string does not .includes the substring being iterated over:

const doFilter = (str, arr) => arr.filter(substr => !str.includes(substr));

console.log(
  doFilter("apple banana", ["apple", "banana", "orange", "grape"]),
  doFilter("1 3 b c", ["1", "2","3", "a", "b", "c"]),
);

I think you need array.filter(substr => !string.includes(substr)) to remove the matching items.
