hi
welcome to programming
if you've never learned a program before
you might be wondering what programming
actually is
well when we write a program we're
giving the computer a series of commands
that kind of look like a weird form of
english you can think of a computer as a
very obedient dog listening to your
every command and doing whatever you
tell it to do
so what's so cool about programming well
it really depends on what you think is
cool
because as it turns out you can use
programming for almost everything
programs control robots that can take
care of patients
and my favorite robots that can roam
around mars and look for water on the
surface programs help self-driving cars
know which way to turn
which is pretty important
programs help doctors cure diseases by
processing huge amounts of medical data
programs can be really fun games like
doodle jump angry birds minecraft
programs make it possible for pixar to
put out their awesome 3d animated movies
and for movies like harry potter to have
such cool special effects
what's your favorite movie i bet that a
computer helped make it somehow programs
are behind the websites and the apps
that you use every day all the time like
google maps and wikipedia and youtube
and of course where you are now khan
academy
here on khan academy you'll learn how to
write javascript programs to make
drawings animations and games and that
will be a great start towards creating
whatever you're imagining in your head
i know it might be hard to see how a
drawing program
relates to programs for robots or curing
diseases
but believe it or not the same basic
concepts are used by pretty much every
programmer in every program
once you learn to program javascript
you'll be able to learn other
programming languages much more easily
now you just gotta keep going
