One of most important programming languages.
ES6 will have some good and bad parts, again.
ES6 will become real functional language.
WeakMap – it works like objects should have worked. Anything could be a key. Stupid name.
Class – Most requested, by Java programmers.
Generators – Adding lot of complexity.
Object.create instead. Stopped using
Object.create too – because stopped using
this (forbidden in AdSafe.)
AdSafe – simple, just forbid to use
Caja by Google
null – doesn’t make sense to have both
undefined all the time.
Stopped using falseness – originally created to support C style programming, which doesn’t have boolean, and
0 was used for
for -> array.forEach is better.
for in -> Object.keys is better.
In ES6 will be both same fast.
Dart and typescript is not forward looking programming language we would like to leave for our children.
> Lambdas are good idea.
Last good system language was C.
Most popular languages today are application languages.
Usually your taxonomy of classes is broken. When you get away from classes, you avoid errors.
Prototypal inheritance – big advocate, not anymore. Better for memory, but was useful before we got GB of memory in our pocket.
Advocate class free programming.
Stop using stacks, start using heaps - solved.
Passing in separate params is to limiting.
Mixing data and methods was transitional step, but we should generally avoid it.
Ints are bad.
Discard what doesn't fit and don’t tell anybody - worst strategy.
