Question

If I have something like

[Object(id:03235252, name:"streetAddress"), Object(id:32624666, name:"zipCode")...]

How can I remove an object from that array that has name set to “zipCode”?

If you need to modify the existing Array, you should use splice().

for (var i = array.length - 1; i > -1; i--) {
    if (array[i].name === "zipCode")
        array.splice(i, 1);
}

Notice that I’m looping in reverse. This is in order to deal with the fact that when you do a .splice(i, 1), the array will be reindexed.

If we did a forward loop, we would also need to adjust i whenever we do a .splice() in order to avoid skipping an index.
