[jQuery] Synchronous call in JQuery?

[Mesquite]

Is there a JQuery way to execute a custom function 'after' another
custom function is executed?
The second function must wait until the first one has finished. (Not
asynchronous but synchronous)
Important: I don't want place the call to the second function in the
first one.

for example:

doSomething1();
doSomething2();

function doSomething1() {
}

function doSomething2() {
}
