1. Beyond JavaScript @jakobmattsson jakobmattsson.se
2. Everything is fucking dynamic
3. JavaScript is not JS
4. Static checking was good - Casting was evil
5. New perspectives
6. Combine the best of two worlds!
7. It failed
8. Open up a new set of possibilities
9. The dynamic languages disappoints
10. list.select { |x| x > 0 } filter (> 0) list list.filter(function(x) { return x > 0 })
11. && ||
12. EVERYTHING IS AN OBJECT!!!
13. What can Blub do?
14. What can Blub do?
15. What can Blub do? What can’t Blub do?
16. It’s not about a particular solution
17. It’s about doing as little as possible
18. A dynamic language should be moldable
19. The best part
20. But this conference is about JavaScript!
22. 1. Full of stupid shit
23. 1. Full of stupid shit 2. Platform for everything
24. 1. Full of stupid shit 2. Platform for everything 3. Has amazing ideas
25. Call by name
26. && = lazyfunction(a, b) { if (execute(a)) { if (execute(b)) { return true; } } return false; }; Call by name
27. Operators on steroids
28. v = a + b unless x > y Operators on steroids
29. v = a + b unless x > y => (x > y).unless(v = a + b) Operators on steroids
30. Syntax unification
31. list.filter(> 0) Syntax unification
32. msg = { name: ’<’, arguments: [ { value: 0 } ] }; Syntax unification
33. filter = lazyfunction(msg) { var r = []; this.forEach(function(e) { if (e.send(msg)) { r.push(e); } }); return r; } Syntax unification
34. We are not there yet
35. Safety? Performance?
36. What can Blub do? @jakobmattsson jakobmattsson.se What can’t Blub do?
