Extremely exciting. Just couldn't believe what I just read. That's something
I never expected anything but "sync" mode.
Thanks a bunch.
Oh and happy new year all.

Async is to do with how it handles the process of loading. Take the
following code for example:
{
some code
some more code
even more code
a "load call" <!--- this is the one
just a few more lines of code
almost there
the last line
}
Here's how the code would finish executing in "sync" mode:
{
1 some code
2 some more code
3 even more code
4 a "load call" <!--- this is the one
5 just a few more lines of code
6 almost there
7 the last line
}
If the loading takes too long, "async" may look like this:
{
1 some code
2 some more code
3 even more code
7 a "load call" <!--- this is the one
4 just a few more lines of code
5 almost there
6 the last line
}
This is because in "async" mode, the load function returns instantly even if
it is still loading. For this treason, it is possible to continue executing
the rest of the code WHILE the load function is running. If we are using it
to load code the is required further down, it is important to make sure it
is loaded before we continue, this is where "sync" mode is used. This
requires that the load function is finished before it returns and we
continue with the rest of our code.
I hope this makes sense and helps a little. :)
