Question

In contact with

If we execute the code

var a = {"cname":456};
var parametr = 12331;
a = a + {"name":123, "lol":76478167};
a = a + {parametr: 222};
return a;

Get

response: {cname: 456, name: 123, lol: 76478167, parametr: 222}

I need the result to be like this:

response: {cname: 456, name: 123, lol: 76478167, 12331: 222}

You need to insert the parametr variable into the key name. How can I do that?
