run function one by one in javascript

[perhapscwk]

I have a function similar as below, when function run() is calling,
it will run startA and startB at the same time, how to make
sure startB will run only after startA completed?

 
Function run() {
 
function startA();
function startB();
 
}

Rather than declaring functions, call them:

function run() {
    startA();
    startB();
}

[perhapscwk]

yes..but but both startA and startB process at the same time..

Can you post the code or at least explain what they do.

[perhapscwk]

startA will return a value.

then StartB use it to process.

Can you post the code or (if it's too long) a link.
