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

@Iulian Pinzaru's answer was almost exactly what I needed, but it doesn't work if your objects have any null values. This version fixes that.

function  deepSearch (object, key, predicate) {
  if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) return object

  for (let i = 0; i < Object.keys(object).length; i++) {
    const nextObject = object[Object.keys(object)[i]];
    if (nextObject && typeof nextObject === "object") {
      let o = deepSearch(nextObject, key, predicate)
      if (o != null) return o
    }
  }
  return null
}
