Remove an object from array with objects and functions

Question

I have an object array:

[ 
    { name: 'one',   value: '1' },
    { name: 'two',   value: '22' },
    { name: 'three', value: '333' },

    add:    [Function],
    delete: [Function]
]

How can I delete an object with name: 'two'?

[ 
    { name: 'one',   value: '1' },
    { name: 'three', value: '333' },

    add:    [Function],
    delete: [Function]
]

I've tried splice() and delete, but they don't work in my case.

Also tried to iterate the whole array and rebuild it depending on what I want to remove, but that doesn't seems like a good approach...

Generally, I want to implement something like an ArrayList to allow easy find/add/remove/modify.

Maybe I structure my code wrong?

You appear to be using object literal notation inside an array - is this intentional? — Qantas 94 Heavy

@Qantas94Heavy - It definitely sounds intentional... "remove an object from array with objects and functions". — James Allardice

@Qantas94Heavy - Oh, sorry, I see what you mean now. Yeah that must be a typo in the question (perhaps copied from the console, since it also just says [Function]). — James Allardice

You can use the .filter() method, which returns a new array containing only the items that pass the test:

var arr = arr.filter(function (obj) {
    return obj.name !== "two";
});

Nice and elegant, with the proviso that he remove the object notation which is breaking his array.
