pattern jacket an asynchronous javascript duty synchronous

i'm operative javascript api where many functions asynchronous. api contracting subset functionality manipulate sqlite3 databases. i know settlement preference things async retard yield manageable user interface. conditions i know use async api calls govern fast. given box i'd yield developers cleaner easier coupling api army synchronous calls.

here's async call

db.executesql(sqlstatement, function(result) {
  // something result
});

and here's i'd means do

var outcome = dbwrapper.executesql(sqlstatement);
// something result

is there settlement pattern/way this? combined related formula instance preferred. aim platform/broswer mobile safari iphone.
