jquery - javascript filter array of objects

Question

I have an array of objects and I'm wondering the best way to search it. Given the below example how can I search for name = "Joe" and age < 30? Is there anything jQuery can help with or do I have to brute force this search myself?

var names = new Array();

var object = { name : "Joe", age:20, email: "[email protected]"};
names.push(object);

object = { name : "Mike", age:50, email: "[email protected]"};
names.push(object);

object = { name : "Joe", age:45, email: "[email protected]"};
names.push(object);

A modern solution with Array.prototype.filter():

const found_names = names.filter(v => v.name === "Joe" && v.age < 30);

Or if you still use jQuery, you may use jQuery.grep():

var found_names = $.grep(names, function(v) {
    return v.name === "Joe" && v.age < 30;
});
