Accessing a JavaScript's object property without knowing that property name

Question

Situation

I have a JSON object which is returned. And Below is an example of one. The who in this particular example can change to what

Answer 1

Object.keys(m)[0] should return the first enumerable property name in the object m.

So if m = {"who": "Arthur"}; then m[Object.keys(m)[0]] will be "Arthur".

Alternatively: Object.values(m)[0]. See Object.values
