How to find the id looping through the array of objects using typescript and react?

Question

i have data like below,

const items = [
    {
        id: \'1\',
        color: \'green\',
        name: \'item1\',
        polygons: [
            {

You can run nested loops, or you can access the subitems directly and use some or filter but if you wanted full recursion here's a fairly verbose gist for the sake of explaining

const iterate = (obj) => {
  // loop through object properties
  Object.entries(obj).forEach(([key, value]) => {
    if (obj.hasOwnProperty(key)) {
      // do something with the current iteration
      
      if (typeof value === 'object') {
        // if the property value is an object then iterate into that object
        iterate(value)
      }
    }
  });
};

iterate(items);
