There was a time when the word JavaScript reminded developers about form validations or adding animation in web pages. However through time, Javascript has grown to be one of the most popular languages in the development world with its implementation usage in back-end and front-end development. With the rise of Javascript front-end frameworks such as AngularJS, React JS or VueJS, as well as the invention of cross-platform mobile development frameworks such as React Native, Native Script, Javascript once again has proved its popularity and ability to become the most powerful language that truly breaks the platform barrier and allows developers to solve problems in various platforms.

12. Javascript popularity
and how it becomes
so popular?
Story
Through few surveys
and reports, you can see
the popularity of the
language and its various
frameworks in today’s
development world.

13. How popular is JS?

14. Stack overflow
Developer Survey
2018 showed:
For the 6th
year in a
row, JavaScript is
the most commonly
used programming
language.

15. It says:
Node.js and AngularJS
continue to be the most
commonly used
technologies in this
category, with React
and .Net Core also
important to many
developers.

16. Continue:
React & NodeJs stays
number 2nd
and 4th
in
the list, showing the
love of developers to
our JS Frameworks.

20. NodeJS - the lift for JS
popularity
- Node.js is actually not a framework,
but a runtime environment that
allows to execute JavaScript on the
server side.
- NodeJS is fast, easy to learn, have an
active community available for
support.
- Especially popular in real-time
applications or when we seek a fast
& scalable solution

the inventor of NodeJS.
He introduced NodeJS
in Nov 2009.

21. Javascript
implementations and
what make it so
appealing? Since the invention of
NodeJS, Javascript has
become more powerful
and is used in most type
of applications in today
world.

22. You can develop almost everything with Javascript
➔ Backends through NodeJS
ExpressJS, KoaJS, Meteor etc.
➔ Frontends
ReactJS, AngularJS, VueJS, EmberJS etc.
➔ Mobile Apps
React Native, Ionic, Native Script, Weex etc.
➔ Desktop Apps
Electron.
➔ Training & deploying ML Models
TensorflowJS

23. NodeJs – who use it?

24. React websites
There are many of them, but here are a few famous
ones
➔ Facebook - social network service
➔ AirBnb - biggest online community marketplace
➔ Product Hunt - discover new products
➔ Atlassian - domain provider

27. What makes JS so appealing?
- Increase no of development
environments/platforms
- Better specifications you can write JS in (e.g.
adding new language features through
releasing of ECMAScript versions)
- Browsers quickly adapt to the new
specifications and support it
- More options you want to write JS, without,
well, writing JS (e.g. TypeScript, ClosureScript
or Elm etc.)
- And good demands out there for the skills
“If you know JavaScript, you can
write code for anything”

29. Where do I start?
You can learn everything from … GOOGLE :) Get
started with these first
➔ w3schools.com
Best place to learn the basic
➔ javascript30.com
30 day vanilla JS coding challenge
➔ jsfiddle.net
Quick and easy place to test your JS codes
➔ Jump on Google for more specific
framework learning :)

30. Once you learn the basic, try this cool open-source project...

34. So what do you think?
You you like your
school/uni to
teach you about
these JS
frameworks?
How many of you
have worked on
JS frameworks?
If you haven’t, do
you think it’s
interesting to
learn JS now?
Then it’s time for Q&A session
