Filter an array based on an object property [duplicate]

Question

You could use array’s filter() function:

function filter_dates(event) {
    return event.date == "22-02-2016";
}

var filtered = events.filter(filter_dates);

The filter_dates() method can be standalone as in this example to be reused, or it could be inlined as an anonymous method – totally your choice =]

A quick / easy alternative is just a straightforward loop:

var filtered = [];
for (var i = 0; i < events.length; i++) {
    if (events[i].date == "22-02-2016") {
        filtered.push(events[i]);
    }
}
