Filter multidimensional array with objects

Question

With an array like the following, how can I filter objects based on the texts.id? For example if I wanted to return this very same array without the texts object reffering to the id 123 how would I go about it? I have access to the id I want to filter out and also the name of the object where its located. I have been trying to figure this out but I am not sure this is doable with the filter method only. Thanks in advance to anyone that helps.

[
 0: Object {
  name: 'Name 1',
  texts[
   0: Obj{
    id: '123',
    body: 'test message'
   },
   1: Obj{
    id: '456',
    body: 'test message 2'
   }
  ]
 },

 1: Object {
  name: 'Name 2',
  texts[
   0: Obj{
    id: '789',
    body: 'test message3'
   },
   1: Obj{
    id: '101112',
    body: 'test message 4'
   }
  ]
 }
]

You probably need to use two loops: one to iterate over the outer array, and a second to iterate over the inner texts property of each member of the outer array. — old greg

It's not totally clear to me whether you want to remove the entire outer object where the texts array contains an object with a certain id (i.e: in your example, this would remove the whole object with name 'Name 1'), or if you just want to remove the object in the texts array which has a certain id (i.e: leaving the outer object, just removing the object in texts with id 123).

The former has been answered by @lissettdm above, but if it's the latter, you could do something like this:

const filter = "123";
entry.forEach(item => item.texts = item.texts.filter(text => text.id !== filter));

Yes I want to remove the object inside texts (id and body) where the id equals the id I am searching for and return the rest of the array exactly as it was.

Hi there, what I've posted here should work then :) You can just replace entry by whatever the name of the variable containing your multi-dimensional array of objects is.

Yes that's what I did, thanks a lot mate, already accepted it as the correct answer.

Yes, it is possible using Array.prototype.filter() and Array.prototype.find()

const entry = [{name: "Name 1",texts: [{id: "123",body: "test message"},{id: "456",body: "test message 2"}]},{name: "Name 2",texts: [{id: "789",body: "test message3"},{id: "101112",body: "test message 4"}]}];
    
const filter= "123";
const output = entry.filter(item => item.texts.find(text=> text.id===filter));
    
console.log(output);
