How to “properly” create a custom object in JavaScript?
...
There are two models for implementing classes and instances in JavaScript: the prototyping way, and the closure way. Both have advantages and drawbacks, and there are plenty of extended variations. Many programmers and libraries have different ap...
How to .gitignore files recursively
...ipts/special/**/*.js
Should work according to this answer. It also works for me in Windows 7 using Sourcetree 1.6.12.0 and the version of git that it installs (1.8.4-preview20130916).
To gitignore every file and folder under a directory recursively:

Using braces with dynamic variable names in PHP
... you are using this to include a variable (the most useful way IMHO) don't forget to use double quotes. ${'fixedTime$i'} = $row['timeInstance']; gives you a not very useful $fixedTime$i instead of $fixedTime1, $fixedTime2 etc. (Fortunately spotted it almost straight away.)

Because, let's face it, if all yield from does is expand the for loop, then it does not warrant adding yield from to the language and prec...
Which is faster : if (bool) or if(int)?
...helps to illuminate that when choosing a variable type, you're choosing it for two potentially competing purposes, storage space vs. computational performance.

A better similarity ranking algorithm for variable length strings
I'm looking for a string similarity algorithm that yields better results on variable length strings than the ones that are usually suggested (levenshtein distance, soundex, etc).
...
Why does ++[[]][+[]]+[+[]] return the string “10”?
...ase it will come down to +"" or 0 (see specification details below).
Therefore, we can simplify it (++ has precendence over +):
++[[]][0]
+
[0]
Because [[]][0] means: get the first element from [[]], it is true that:
[[]][0] returns the inner array ([]). Due to references it's wrong to say [[]]...
