JavaScript - wait function to execute completely

I have 2 JS functions:

check_fields() and send_form() .

send_form() function should call check_fields() function:

function check_fields()
{
   //do an ajax request causing a little delay
   //return true in case of valid fields or false in case of error(s)
}

function send_form()
{
if ( !check_fields() )
            return;
//do stuff here
}

The problem is that send_form() function doesn't execute quickly, so I have to know when it had executed completely. How could I know that?

PS: If I remove the ajax request, everything works fine.

read up on using `callbacks` or `promises` - plenty of questions on both here at SO – Jaromanda X Oct 15 '15 at 14:10
