What does `image: HTMLImageElement` do?

I tried writing image: HTMLImageElement in my browser console today. I expected an error would occur, but it didn't.

This does not declare a variable as var image: HTMLImageElement on TypeScript does, and it also does not define a property as var x = { image: HTMLImageElement } does. It seems that this actually does nothing. What does this syntax do?

Unless within an object, text followed by a colon in JavaScript is a labelled statement. An example labelled statement which you will have probably seen before is:

<a href="javascript: void(0)">

In this case, javascript is the label and void(0) is the statement. In your case, image is the label and HTMLImageElement is the statement.
