filter array with an array

/* Here's an example that uses (some) ES6 Javascript semantics to filter an object array by another object array. */

        // x = full dataset
        // y = filter dataset
        let x = [
            {"val": 1, "text": "a"},
            {"val": 2, "text": "b"},

            ];

        // Use map to get a simple array of "val" values. Ex: [1,4]
        let yFilter = y.map(itemY => { return itemY.val; });

        // Use filter and "not" includes to filter the full dataset by the filter dataset's val.
        let filteredX = x.filter(itemX => !yFilter.includes(itemX.val));

        // Print the result.

  function, you're just doing it inside the filter function. filter applies the code 
  in the callback function to each value of arr, and creates a new array based on your 
  callback functions return values. The return value must be a boolean, which denotes whether an element 
  should be keep or not
