✅

We can recursively search all nodes until we find the match:

getItemRow(id){
    return findNodeWithId(id, this.parents)
}

findNodeWithId(id, rootArr) {
  for (let el of rootArr) {
    if (el.id === id) {
      return el
    }
    if (el.children) {
        const idFoundInChildren = findNodeWithId(id, el.children)
        if (idFoundInChildren !== null) {
          return idFoundInChildren
        }
    }
  }
  return null
}

You could take a recursion and find the object directly or by searching the children array.

const
    find = (array, id) => {
        let result;
        array.some(o => result = o.id === id
            ? o
            : find(o.children || [], id)
        )
        return result;
    },
    data = [{ id: 1, name: "parent 1" }, { id: 2, name: " parent 2", children: [{ id: 5, name: "parent-children 5" }, { id: 6, name: "parent-children 6", children: [{ id: 7, name: "parent-children-children 7" }, { id: 8, name: "parent-children-children 8", children: [{ id: 9, name: "parent-children-children-children 9" }, { id: 10, name: "parent-children-children-children 10" }] }] }] }, { id: 3, name: "parent 3" }, { id: 4, name: "parent 4" }];

console.log(find(data, 9));
