Iterate a JSON and access keys blindly. Angular2

I return from the beginning to Restructure all the question:

I will receive the detail of a Master / detail of AgGrid, the problem is that I do not know how many elements I will receive or what is the key that I will receive, since they will change the elements and keys every x time.

In the 1st image, it is the result I want to obtain, I display the Master and it can be seen mocked that I get 4 groups (In red) (which may vary the number of elements that I will receive.)

And each group can have an x number of elements.

I remember that all this is the detail.

Image 2 is what I'm barely getting at the moment.

The data I have to take out without knowing your password, for example

value['name'] value['text']

I'm not good because as I said, the data will come different every x time

The problem is no longer to get that data, that just barely as you can see, I'm already accessing the attributes of the children with a series of objects. Foreach

The structure of the JSON as an example:

 "masterdetail": [ {
          "child1": [
            {
            }
          ],
          "child2": [
            {
            }
          ],
         }]

Remembering that 'x' childs can come and each child can come with 'x' fields.

The problem comes to me when I want to SHOW it in the html (by console it does not work for me)

This is done with this.detailCellRendererParams

template: function(params) {

  --->>>  MIS FOR EACHS.

  return (
          '<div class="aggrid--full-row-container"> ( el contenido )'
         );
      }
    };
  }

I come from PHP and JSP and I have always been able to insert a html output in the foreach, but here, if I put the foreach inside the return it does not leave me.

Then, and as a summary , get the data without the keys, I'm already slowly removing it with the console.log, but showing them inside the return I do not know how to do it because it will not let me put the foreach inside the return.

Thanks to everyone!

Thanks to the help of Pablo Lozano and JackNavaRow.

To show in the detailGridOptions a Json which is not known the amount of elements that will bring and each elements you do not know the key that you will have. The solution is:

        const objects = params.data.masterdetail[0];
        const keys = Object.keys(objects);
        let value;
        let content;
        let childKey;
        let result = '<ul>';

        keys.forEach(key => {
          value = objects[key];
          content = value[0];
          console.log('todo el Hijo ', content);
          childKey = Object.keys(content);
          childKey.forEach(childs => {
            console.log('Atributos', childs);
            result = result + '<li><label>' + childs + ':</label>' + content[childs] + '</li>';
          });
          result = result + '</ul>';
        });
        // console.log('template ', params.data.masterdetail);
        return (
          '<div class="aggrid--full-row-container">' + result + '<div ref="eDetailGrid" </div>' + '</div>'
        );

Although it would be necessary to give a bit of CSS for the styles, I already show the data. Thank you very much =)
