i read little hoisting , reordering , seems java vm may choose hoist expressions. read hoisting of function declarations in javascript. first question: can confirm if hoisting exist in c, c++ , java? or compiler/optimization dependent? i read lot of example c codes put variable declarations on top, before assert or boundary condition . thought little faster asserts , boundary cases before variable declarations given function terminate. main question: must variable declarations on top in context? (is there hoisting @ work here?) or compiler automatically optimize code checking these independent asserts , boundary cases first (before irrelevant variable declaration)? here's related example: void mergesort(struct node** headref) { struct node* a; struct node* b; if ((*headref == null) || ((*headref)->next == null)) { return; } frontbacksplit(*headref, &a, &b); mergesort(&a); mergesort(&b); *headref = so...

i need run function once every element matches .myclass - needs run in order of how many parents each element has. $('.myclass').each(function(index){ //my code }); the thing can think of doing doing each() function before 1 appends data-sort attribute based on parents().length() surely there's better way that? map number of parents along element array of objects. sort , iterate result. var els = $('.myclass'); var data = els.map(function(index, el){ return {el: el, pars:$(el).parents().length}; }).toarray() .sort(function(a,b) { return a.pars - b.pars; }); $.each(data, function(i, obj) { var el = obj.el; // el });
