Script Preparation code:

var types = ['Type1', 'Type2', 'Type3'];
var getType = (i) => types[i % 3];
var fillList = (numberOfItems) => {
    const list = [];
    for (var i = 0; i < numberOfItems; i++) {
        list.push({
            name: `dataItem${i}`,
            value: i,
            type: getType(i)
        });
    }
    return list;
};

var dataItems = fillList(100000);

var dataItemsOfType1And2 = dataItems.filter(dataItem => dataItem.type === types[0] || dataItem.type === types[1])

Tests:

Filter 100000 items with include
dataItems.filter(dataItem => !dataItemsOfType1And2.includes(dataItem));
Filter 100000 items without include
dataItems.filter(dataItem => dataItem.type !== types[0] && dataItem.type !== types[1]);
