javascript - How to access first element of JSON object array?

Question

I exptect that mandrill_events only contains one object. How do I access its event-property?

var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' }

Answer 1

var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' }

console.log(Object.keys(req)[0]);

Make any Object array (req), then simply do Object.keys(req)[0] to pick the first key in the Object array.
