Is there a way to return to an early deferred promise?

Question

So, I have a promise that contains several checks like this

function test(){
    var deferred = q.defer()
    var passed = false
    if(!passed){
        deferred.reject("Don't proceed")
        //return
    } else {
        if(!passed){
            deferred.reject("Don't proceed")
        } else {
            if(!passed){
                deferred.reject("Don't proceed")
            } else {
                setTimeout(function(){
                    console.log("Hello");
                    deferred.resolve()
                }, 100);
            }
        }
    }
    return deferred.promise
}

It looks bad because there is a pyramid below. I am wondering if there is something like a return to "q" that can improve the code? For example, for example:

function test(){
    var deferred = q.defer()
    var passed = false
    if(!passed){
        deferred.reject("Don't proceed")
        return
    }
    if(!passed){
        deferred.reject("Don't proceed")
        return
    }
    if(!passed){
        deferred.reject("Don't proceed")
        return
    } 
    setTimeout(function(){
        console.log("Hello");
        deferred.resolve()
    }, 100);
    return deferred.promise
}

This definitely does not work, because it is returned before the promise is returned, but I wonder if there is something like a return?

promises, , . Q.reject Q.Promise - . :

function test() {
    var deferred = q.defer()
    var passed = false
    if (!passed)
        return Q.reject("Don't proceed");
    if (!passed)
        return Q.reject("Don't proceed");
    if (!passed)
        return Q.reject("Don't proceed");
    // else
    return new Promise(function(resolve) {
        setTimeout(function(){
            console.log("Hello");
            resolve();
        }, 100);
    });
}

test Q.fbind, return Q.reject(…); throw …;.

function test(){
    var deferred = q.defer()
    var passed = false
    if(true){
        deferred.reject(new Error("Don't proceed1"))
        return deferred.promise
    }
    if(!passed){
        deferred.reject(new Error("Don't proceed2"))
        return deferred.promise
    }
    if(!passed){
        deferred.reject(new Error("Don't proceed3"))
        return deferred.promise
    } 
    setTimeout(function(){
        console.log("Hello");
        deferred.resolve()
    });
    return deferred.promise
}
