Hallo zusammen, ich bin Pete.

So, wer hat Lust auf ein bißchen O-Notation am morgen?

Ok, ok, wir kommen später dazu .

bevor wir das tun ..

sag ich einfach 'ich bin Pete'

Ich arbeite bei Facebook im Instagram Team

und ich trage zur Bibliothek React bei.

welche - ihr habt es wohl gehört- die ist, welche
eckige Klammern ins Javascript gebracht haben

.. aber ich werde nicht zu viel über React reden
und warum es so unglaublich ist, weil ...

das ist nicht der interessante Teil.

but I wanna talk about is about the idea behind React

and React is a reference implementation of those ideas.

So. This isn't a turial

and I give a focus on ideas and not implementations.

So. I'm gonna talk about the ideas behind react

Some ideas behind other systems

how they're a different kind a

what a different tradeoffs are in there 
are different tradeoffs between them

and hopefully you take some of the ideas and
bring them to your favourite system

or you maybe you think that react is cool
and you can tribute to it.

Lets talk about what makes user interfaces
difficult to build.

Has anyone build an user interface before?

Allright, ok. I figured it.

Was it really easy?

Yeah, testing it was supereasy,

maintainng quality was probably
a joke, right.

It's just a kind a .. always works

He said sarcastically

But you get this a lot

This doesnt feel right

So, you know - even if you use all the test driven
development that you can throw at it

you still have to have a human look at this

this doesnt look right and
this doesnt fell right

and when I click this button and I click this button
and I click this button ... it breaks

There's a lot of things that come in to this

They are human verifiedy but UIs
are also deceptely complex
