If you want to leave it async, your best bet is probably to use
callbacks. For instance:
function abc(){
...code part 1...
setTimeout( function(){MyAsynchronFun(abc_callback, callback_params)} ,
-1); // call the async function
}
function abc_callback(params)
...code part 2...
}
function MyAsynchronFun(callback, callback_params) {
...
setTimeout( function(){callback.apply(this, callback_params)}), -1);
}
