How to draw an object in react?

Question

React

There is an array of the form:

[ {helm: {}}, {arm: {…}} ]
I run through it with a map and get objects of the form
{helm:{def:1,hp:2}
that need to be inserted into the ul in the form: I
<li>{key + ':' + value}</li>
almost managed to do this as follows:

function showStats() {
        for (let item in items) {
            for (let stat in items[item]) {
                return <li>{stat + ':' + items[item][stat]}</li>
            }
        }
    }

but as expected, the function only returns the first value of item and breaks on return. How to draw the object correctly in this case?
