What could possibly be doing sync1() that is preventing the next statement
to NOT be executed? i'ts just ridiculous.
function sync1() receives an array of objects, iterates over it using
.map() and .filter() and returns it again. Nothing inside it is async...
@Vyacheslav Egorov I really didn't understand what you said. Can anyone
answer for sure my question in the first post? Thanks.
