Python allows you to hack list comprehensions to evaluate conditional expressions. For instance, [value_false, value_true][<conditional-test>] Example: >> n = 16 >> print [10, 20][n <= 15] 10 Here n<=15 returns False (which equates to 0 in Python). So what Python i...

SystemJS allows to write and use modular javacsript code that relies on ECMAScript 6 import and export statements.
