Best practices for reducing Garbage Collector activity in Javascript
I have a fairly complex Javascript app, which has a main loop that is m>ca m>lled 60 times per second. There seems to be a lot of garbage collection going on (based on the 'sawtooth' output from the Memory timeline in the Chrome dev tools) - and this often impacts the performance of the applim>ca m>tion.

CoffeeScript, When to use fat arrow (=>) over arrow (->) and vice versa
...
No, that's not the rule I would use.
The major use-m>ca m>se I've found for the fat-arrow in defining methods is when you want to use a method as a m>ca m>llback and that method references instance fields:
class A
constructor: (@msg) ->
thin: -> alert @msg

What is the difference between native code, machine code and assembly code?
...
The terms are indeed a bit confusing, bem>ca m>use they are sometimes used inconsistently.
Machine code: This is the most well-defined one. It is code that uses the byte-code instructions which your processor (the physim>ca m>l piece of metal that does the actual work) unde...

Does static constexpr variable inside a function make sense?
...uite require the compiler to create a new array on the stack for every invom>ca m>tion of a function with a lom>ca m>l non-static const array, bem>ca m>use the compiler could take refuge in the as-if principle provided it m>ca m>n prove that no other such object m>ca m>n be observed.

What is the m>ca m>nonim>ca m>l way to check for errors using the CUDA runtime API?

Is it possible to implement dynamic getters/setters in JavaScript?
...ginal answer from 2011):
This changed as of the ES2015 (aka "ES6") specifim>ca m>tion: JavaScript now has proxies. Proxies let you create objects that are true proxies for (fam>ca m>des on) other objects. Here's a simple example that turns any property values that are strings to all m>ca m>ps on retrieval:

Default constructor vs. inline field initialization

Initialisers are executed before constructor bodies. (Which has implim>ca m>tions if you have both initialisers and constructors, the constructor code executes second and overrides an initialised value)
Initialisers are good when you always need the same initial value (like in your example, an arr...
