Find by key deep in a nested array

Question

Let\'s say I have an object:

[
    {
        \'title\': \"some title\"
        \'channel_id\':\'123we\'
        \'options\': [
                    {
                 


        

Answer 1

If you want to get the first element whose id is 1 while object is being searched, you can use this function:

function customFilter(object){
    if(object.hasOwnProperty('id') && object["id"] == 1)
        return object;

    for(var i=0; i

If you want to get all elements whose id is 1, then (all elements whose id is 1 are stored in result as you see):

function customFilter(object, result){
    if(object.hasOwnProperty('id') && object.id == 1)
        result.push(object);

    for(var i=0; i
