var x;
someModel.findQ({"name":"John"}.then(function(result){
    result// here i have my object, how i can make this in var x ?
});

Answer 1

You can't put it in var x*, that's how JavaScript concurrency works. See my answer here on a broader take on the topic.

someModel.findQ({"name":"John"}.then(function(result){
    // use result here
});

You don't have to nest though, since promises chain

someModel.findQ({"name":"John"}.then(function(result){
    // use result here
    return someOtherModel.findQ({"name" : result.name }); 
}).then(function(obj){
    // you can access the return result of someOtherModel here
});

^{* unless you're willing to try experimental features like generators that aren't in node stable yet.}
