lodash get items from array that does not match array of values

Question

To get items from array that match array of values I use this:

var result =_(response).keyBy('id').at(arrayOfIDs).value();

How can I do the opposite? Get items that does not match array of values.

Answer 1

This is easily done with vanilla JS.

var nonMatchingItems = response.filter(function (item) {
    return arrayOfIDs.indexOf(item.id) === -1;
});

The same approach is possible with lodash's _.filter(), if you positively must use lodash.

ES6 version of the above:

var nonMatchingItems = response.filter(item => arrayOfIDs.indexOf(item.id) === -1);

// or, shorter
var nonMatchingItems = response.filter(item => !arrayOfIDs.includes(item.id));
