What are the mathematical/computational principles behind this game?
...ve written actual C++ code but knowing that vector <something> is an array containing values of type something it's easy to understand what this code does. and this code generates P^2+P+1 cards using P^2+P+1 pictures each containing P+1 picture and sharing only 1 picture in common, for every p...
Is JavaScript a pass-by-reference or pass-by-value language?
...ause a is a memory location passed by value that references a string (char array). Passing structs (similar to js objects) by value in C is allowed, but not recommended. JavaScript simply enforces these best practices and hides the unnecessary and usually undesired cruft... and it sure makes for ...
Performance of static methods vs instance methods
...pact here would be how close data is to related data (value-type fields or array values are closer than data in reference type fields) and patterns of access.

With full SIMD for wider vectors (e.g. counting a whole array)
This bitwise-SWAR algorithm could parallelize to be done in multiple vector elements at once, instead of in a single integer register, for a speedup on CPUs with SIMD but no usable popcount instruction. (e.g. x86-64 c...

What is 'Pattern Matching' in functional languages?
...//invented pattern matching in JavaScript
In foo2, it expects a to be an array, it breaks apart the second argument, expecting an object with two props (prop1,prop2) and assigns the values of those properties to variables d and e, and then expects the third argument to be 35.
Unlike in JavaScript...
