How to remove object with Lodash (find and remove)

Question

I want remove with Lodash, the object with uuid: xxx and not xxx2.

How I can make this with Lodash ?

[
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
]

My actual code:

_.forEach(this.objs, (obj, index, collection) => {
   _.remove(obj, {uuid})
})

You can use filter `arr = arr.filter(({uuid}) => uuid !== 'xxx');` — Hassan Imam, Dec 01 '17 at 10:53

There is _.filter to return a new array or _.remove to change it in place. — , Dec 01 '17 at 10:58

You can simple use _.remove method.

var objects = [
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
];

_.remove(objects, o => o.uuid === 'xxx2');

console.log(objects);

You can also use `_.remove(objects, { uuid: 'xxx2' });` – Ori Drori Dec 01 '17 at 12:01

You can use Array.prototype.filter() for that

let arr = [
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
]


arr = arr.filter(e => e.uuid != 'xxx2');

console.log(arr);
