Find object in array and then edit it

Let's say I have the following array:

var things = [
    {
        id: "12345",
        name: "Bryan"
    },
    {
        id: "55555",
        name: "Justin"
    }
]

I want to search for the object with the id of 55555. But I want to update the name of that particular object to "Mike" from Justin but still keep the entire army intact.

At the moment, I kinda figured out a way to search for the object, but I can't find a solution to actually edit that particular finding.

Could anyone help me out? This is what I have so far:

var thing = things.filter(function (item) {
    return "55555" === item.id;
})[0]
