A quick powerpoint talking about the benefits of using Pyjamas framework instead of Javascript for front-end development.

1. pyjamas Great... yet another web development framework

3. You don't even need Javascript, write everything in Python

4. It will automatically convert your code to Javascript (and even take care of cross-browser issues) What?!

6. Very clean syntax Javascript Python && and || or ! not { } ; var temp=a;a=b;b=temp; a, b = b, a if(1<a && a<5) { if 1<a<5:

8. Already a very popular backend language

9. Makes JS debugging feel like FORTRAN Customary Hello World example: print ”Hello World”

10. Why Python? (cont.) Javascript Python function bubbleSort(items) { var x, y, holder; // The Bubble Sort method for (x = 0 ; x < items.length; x++) { for (y = 0 ; y < (items.length- 1 ); y++) { if (items[y] > items [ y + 1 ] ) { holder = items [ y + 1 ] ; items [ y + 1 ] = items [ y ] ; items [ y ] = holder; } } } def bubbleSort(items): # The Bubble Sort method for x in range ( len ( items )): for y in range ( len ( items )- 1 ): if items [ y ] > items [ y + 1 ]: items [ y ] , items [ y + 1 ] =items [ y + 1 ] , items [ y ] Sorting a list: Javascript Python items.sort() items.sort()

12. Manipulate the DOM

13. Coexist with other JS on same page

14. It's a Python version of GWT
