remove objects with a specific `key: value` from an array
I have an array of object and need to use lodash to remove some of those objects with a specific key: value, for instance:
[
id:1,b:22,
id:2,b:44,
id:3,b:56,
id:4,b:-29
]
I need to remove all object with id of 1 and 3.
i know the way below but was wondering if there is a shorter way:
var array = [
id:1,b:22,
id:2,b:44,
id:3,b:56,
id:4,b:-29
];
_.remove(array, function(n)
return _.includes([ 1,3 ], n.id);
);

Do you really need to mutate the object? it's usually a better idea to work with immutable data.

You could use pullAllBy and provide the elements to be removed as the 2nd parameter.
let data = [id:1,b:22,id:2,b:44,id:3,b:56,id:4,b:-29]
const result = _.pullAllBy(data, [id:1,id:3], 'id')
console.log(result)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>Note that this method mutates the array. If you do not want that use _.differenceBy
Using ES6 and arrow functions + filter to get the values and not mutate the array will also get you somewhat of a short version:
let data = [ id: 1, b: 22 , id: 2, b: 44 , id: 3, b: 56 , id: 4, b: -29 ]
const result = data.filter(x => ![1,3].includes(x.id))
