How to define Object of Objects type in typescript : <p>I have an object to store cached data which should look like this:</p>

<pre><code>private data = {
   'some_thing': new DataModel(),
   'another_name': new DataModel()
}
</code></pre>

<p>I'm trying to assign an empty object to it in the constructor:</p>

<pre><code>this.data = {}; // produces build error
</code></pre>

<p>Basically, i need to define the type of "data" field to say that it's going to have keys with random names and values of type DataModel. I've tried to do this:</p>

<pre><code>private data: Object&lt;DataModel&gt;
</code></pre>

<p>But this is invalid. How would i specify a correct type?</p>
