subtle differences between JavaScript and Lua [closed]
...= operators are of lower precedence than >, >=, <, <=. In Lua, all comparison operators are the same precedence.
Lua supports tail calls.
UPDATE: JS now supports tail calls.
Lua supports assignment to a list of variables. While it isn't yet standard in Javascript, Mozilla's JS engine ...
What is the (function() { } )() construct in JavaScript?
...tion expression. Then look at the last pair (function(){})();, this is normally added to an expression to call a function; in this case, our prior expression.
This pattern is often used when trying to avoid polluting the global namespace, because all the variables used inside the IIFE (like in any ...
How do you express binary literals in Python?
... memory.
Note that leading zeros in a non-zero decimal number are not allowed.
This is for disambiguation with C-style octal literals, which Python
used before version 3.0.
Some examples of integer literals:

How to avoid annoying error “declared and not used”
...s it easier to read code written by other people (you are always sure that all declared variables will be used), and avoid some possible dead code.
But, if you really want to skip this error, you can use the blank identifier (_) :

import (
"fmt" // imported and not used: "fmt"
)

It is run automatically by the runtime the first time it is needed (the exact rules there are complicated (see "beforefieldinit"), and changed subtly between CLR2 and CLR4). Unless you abuse reflection, it is guaranteed to run at most once (eve...
What does O(log n) mean exactly?
...g that the size of the input affects the growth of the algorithm proportionally...and the same goes for, for example, quadratic time O(n2) etc..even algorithms, such as permutation generators, with O(n!) times, that grow by factorials.

How can I multiply and divide using only bit shifting and adding?
...kes a constant multiple of time compared to addition and shifting. If I recall correctly, modern processors, if pipelined properly, can do multiplication just about as fast as addition, by messing with the utilization of the ALUs (arithmetic units) in the processor.
