How it all started

JavaScript growing up

EcmaScript?

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!

Tessel

hardware assembly,
but without the "Assembly"

Tessel

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'! :)

a handful of the open web
in your pocket
