remove object from nested array

Question

I have a familytree looking like this:

{

    \"children\": [{
        \"name\": \"bob\",
        \"children\": [{
            \"name\": \"sam\",
                    


        

Answer 1

You can use JSON.stringify(), JSON.parse(), String.prototype.match() with RegExp /\{"name":"sam".*(?=\]\}\]\})/ to match property having property "name" with value "sam" remove remainder of string until ]}]} is portion of string with String.prototype.replace()

var res = JSON.parse(
  JSON.stringify(data)
  .replace(JSON.stringify(data).match(/\{"name":"sam".*(?=\]\}\]\})/)[0]
  , ""
  , ["children"])
);

var data = {

  "children": [{
    "name": "bob",
    "children": [{
      "name": "sam",
      "children": [{
        "name": "mike",
        "children": [{
          "name": "elias",
          "children": []
        }, {
          "name": "rodriguez",
          "children": []
        }]
      }]
    }]
  }]
}

var res = JSON.parse(
  JSON.stringify(data)
  .replace(JSON.stringify(data).match(/\{"name":"sam".*(?=\]\}\]\})/)[0]
  , ""
  , ["children"])
);

console.log(data)

document.querySelector("pre").textContent = JSON.stringify(res, null, 2);
