is there way this: class example { public: const int dontmodifyme; example() { // setup dontmodifyme.. dontmodifyme = getvaluefordontmodifyme(earliersetup); } } example ex; cout << ex.dontmodifyme; // works ex.dontmodifyme = 4 // error if dontmodifyme didn't need setup, use member initialization list. there way around doesn't require explicit getter/setter methods? something have used in past along lines of: class example { int m_thevalue; public: const int &thevalue = m_thevalue; } this allows edit value internally via m_thevalue while keeping constant interface available in "public" realm. similiar in effect of getter/setter method, doesn't require actual usage of said methods.

out of curiosity: the mdn taught me how shortcut function application this: trim = function.prototype.call.bind(string.prototype.trim) join = function.prototype.call.bind(array.prototype.join) now, can map trim , not join reason. join takes ',' default argument (separator), should fine, instead uses array index: > trim = function.prototype.call.bind(string.prototype.trim) call() > [' a','b '].map(trim) ["a", "b"] > join = function.prototype.call.bind(array.prototype.join) call() > [['a','b'],['c','d']].map(join) ["a0b", "c1d"] why? also, if wanted different separator? passing bind doesn't work, since prepended existing arguments (at time 1 of elements of list on map). takes role of strings join , strings join act separators if there separate: > joins = function.prototype.call.bind(array.prototype.join,';') call() > [['a','b...
