I have an array of objects like:

var a = [

  {id: 1, name: 'A'},

  {id: 2, name: 'B'},

  {id: 3,  name: 'C'},

  {id: 4, name: 'D'}

];

And Ids array which i want to remove from array a :

var removeItem = [1,2];

I want to remove objects from array a by matching its ids, which removeItem array contains. How can i implement with lodash.

I Checked lodash's _.remove method, but this need a specific condition to remove an item from array. But i have list of ids which i want to remove.

As you mentioned you need the _.remove method and the specific condition you mention is whether the removeItem array contains the id of the checked element of the array.

var removeElements = _.remove(a, obj => removeItem.includes(obj.id));

// you only need to assign the result if you want to do something with the removed elements.

// the a variable now holds the remaining array
