is there cross browser way of implementing console.log functionality, official supported browser @ 1 of client still ie7/ie8.

as development tested firefox debugging capabilities, come across issues on release obscure flow still left un commented console.log statements doesn't fly ie

looking kind of, if use elegant way, love learn.

function log(msg){    if(ie) alert(msg)    else      console.log(msg) } 

here option:

if (typeof console === "undefined" || typeof console.log === "undefined") {       console = {};     console.log = function(msg) {         alert(msg);     }; } 

edit: noted others, should make sure console.log doesn't end in production code.
