How it all started

JavaScript growing up

EcmaScript?

• The standardized name for JS
• First version in 1997
• Latest draft (ES6, now ES2015)
  Slated for release & approval in June
• Lots of features already in the browser,
  or use transpilers to access latest functionality
• Yearly releases planned from now on
   

W3C DOM

• Access to browser internals via standardized, platform-independent API interfaces
• Standardization started within W3C in 1997
• Requests, animations, rendering etc. demistified
• Replacing dated API-s with new, more flexible & robust ones (eg.: Fetch)
• Decoupling the DOM from the browser:
  bringing DOM access to node via JSDOM

Web seeps into the HW layer

• One of the first (and to date most supported) web api: Geolocation
• Other hardware API-s appear (Battery)

A big leap

JavaScript conquering the
frontend, backend & apps

Widespread JS

• As node.js charges ahead, JavaScript expands and for the first time it encompasses the full web stack.
• Front-end frameworks pop up on every corner, offering more and more native-like experiences.

JavaScript of Things

and the heralds of a new era

IoT HW meets JavaScript

• Node on the Raspberry Pi, Arduino?
• Jonny five to the rescue!

@NTHGergo has a nice intro to NodeBots!

Tessel

hardware assembly,
but without the "Assembly"

Tessel

tessel.io

Tessel

• Dedicated hardware, running "JS"*
• Node compatible
• NPM compatible!
• Out of the box hardware modules
• Support for expansions/generic IO!

* actually it compiles to LUA, but whatevz'! :)

Firefox OS

a handful of the open web
in your pocket

Firefox OS

Mozilla's open-source, web-based operating system, now available worldwide in
28 countries and on 15 devices.

Phone to IoT
in 20 minutes

PS: please do not literally abuse phones,
they have souls you know...

JanOS

never stop exploring

The odd one out:

Please meet the world's most inexpensive JS IoT hardware

Jan OS source is (of course) on GitHub!

JanOS

• Whack an inexpensive phone apart, have myriad of sensors right at your fingertips!
• Runs JavaScript
• Use well-documented Open Web API-s that are on standards track
• Download and flash a ready-made image from janos.io or build your own firmware!

Future of the
Extensible Web

onwards & upwards!

Laying down the foundations

• "Bedrock" API-s for enabling web developers and removing the "magic" from what browsers do:
  Fetch, Service Workers, CSS Houdini project etc.
• Aggressive standardization
• Cross-browser interoperation
• Bridging the gap with native
  (both features & performance!)

Building an Extensible Web

• Building an Extensible Web
• Interoperability & standards focus
• Browser vendor openness & cooperation

Join us in February!

from Jan himself!
