React-native get method return value

Question

I have the following method in my class MakeRequest.js:

export default class MakeRequest{
    send() {
        var data = 'foo';
        var data2 = 'bar';
        return [data, data2];
    }
}

I am trying to access data and data2 from a different class:

(array) => MakeRequest.send(JSON.stringify(query));
alert(array[0]);

The error message displayed is

Can't find variable: array

Why is 'array' not accessible?

Answer 1

array is out of scope. Your lambda ends with the send call. If you're wanting to alert within it, and not return the output of that method call, do something like this:

(array) => {
    MakeRequest.send(JSON.stringify(query));
    alert(array[0]);
}
