JavaScript recursive search in JSON object

Question

I am trying to return a specific node in a JSON object structure which looks like this

{
    \"id\":\"0\",
    \"children\":[
        {
            \"id\":\"

I would try not to reinvent the wheel. We use object-scan for all our data processing needs. It's conceptually very simple, but allows for a lot of cool stuff. Here is how you would solve your specific question

const objectScan = require('object-scan');

const findNode = (id, input) => objectScan(['**'], {
  abort: true,
  rtn: 'value',
  filterFn: ({ value }) => value.id === id
})(input);

const data = {
  id: '0',
  children: [{
    id: '1',
    children: [
      { id: '3', children: [] },
      { id: '4', children: [] }
    ]
  }, {
    id: '2',
    children: [
      { id: '5', children: [] },
      { id: '6', children: [] }
    ]
  }]
};

console.log(findNode('6', data));
// => { id: '6', children: [] }
