How to check if the JSON data is one object or an array of objects?

Question

I got server responsed JSON data:

var data = SERVER_RESPONSE;

this data could be an object {id: 12, name: John},

it could also be an array of objects [{id: 12, name: John}, {id: 22, name: OMG}]

In Javascript, how can I check if the JSON data is one object or an array of objects?

Answer 1

You could use the following test:

if (data instanceof Array) {
    // data is an array
} else {
    // it is not an array
}
