Slides from a tech-demo on 2.11. @Tampere

1. Craft Beer & Clojure
2.11.2017

2. The Beer!

3. Clojure
• Strongly typed, dynamic language
• Functional & immutable at the core
• Homoiconic (code is data)
• Macros & runtime polymorphism
• REPL Workflow
• Main targets are JVM & JS
– Thank you for all the libs :)

4. Why Clojure?

5. Adrian Cockcroft
A lot of the best programmers and
the most productive programmers
I know are writing everything in
Clojure and swearing by it, and
then just producing ridiculously
sophisticated things in a very
short time. And that programmer
productivity matters.

(1.5y project, 5+ developers)

10. Clojure in Finland
• Lot’s of startups using Clojure(Script)
• Many public sector projects written in Clojure
• Most software consultancies use it (Metosin, Solita,
Siili, Reaktor)
– Edge in both recruiting & gigs
• Active meetup groups & ClojuTRE
• Twitter: https://twitter.com/clojurefinland
• Slack: https://clojurians.herokuapp.com
