Adequately Good - JavaScript Module Pattern: In-Depth - by Ben Cherry

Adequately Good - JavaScript Module Pattern: In-Depth - by Ben Cherry: "Anonymous Closures

This is the fundamental construct that makes it all possible, and really is the single best feature of JavaScript. We'll simply create an anonymous function, and execute it immediately. All of the code that runs inside the function lives in a closure, which provides privacy and state throughout the lifetime of our application.

(function () {
// ... all vars and functions are in this scope only
// still maintains access to all globals
}());
Notice the () around the anonymous function. This is required by the language, since statements that begin with the token function are always considered to be function declarations. Including () creates a function expression instead.

Adequately Good - JavaScript Module Pattern: In-Depth - by Ben Cherry

Adequately Good - JavaScript Module Pattern: In-Depth - by Ben Cherry: "The module pattern is a common JavaScript coding pattern. It's generally well understood, but there are a number of advanced uses that have not gotten a lot of attention. In this article, I'll review the basics and cover some truly remarkable advanced topics, including one which I think is original."

JS Memory

JS Memory: "Let take a look at what V8 actually does when it runs something like:

function foo(x) {
if (x) {
var hi = "str";
}
return hi;
}
First of all, allocation of string "str" does not happen every time you run this function. It is allocated once by a parser. Every time you execute this code the very same string object will be used again and again. It looks like this:

hidden class
length
hash
str■

JorenSix/TarsosDSP · GitHub: "TarsosDSP is a Java library for audio processing. Its aim is to provide an easy-to-use interface to practical audio (signal) processing algorithms implemented, as simply as possible, in pure Java and without any other external dependencies. TarsosDSP features an implementation of a percussion onset detector and a number of pitch detection algorithms: YIN, the Mcleod Pitch method and a “Dynamic Wavelet Algorithm Pitch Tracking” algorithm. Also included is a Goertzel DTMF decoding algorithm, a time stretch algorithm (WSOLA), resampling, filters, simple synthesis, some audio effects, and a pitch shifting algorithm.
