Shorten up console.log() in JavaScript
Debugging in JavaScript can be irritating sometimes, repeatedly typing console.log() is an annoyance. I always make a shorter shortcut for it to save my time.
function d(msg) {
console.log(msg);
}I'd like to make it as short as possible, so I choose a single letter function name ;)
Next time I need to debug some variable, I just need to type d(someVariable). Great, it's now prettier :p

ever tried:
var d = console.log ?
@greelgorke Well, var d = console.log won't work, because it will trigger a TypeError:)
Personally I don't mind using console.log, since, well... I use snippets. Anyway, if you want to be a little bit more elastic and pass all arguments to aliased console.log method, you could use something like that:
window.log = function(){
log.history = log.history || []; // store logs to an array for reference
log.history.push(arguments);
if(this.console){
console.log( Array.prototype.slice.call(arguments) );
}
};
// source: https://github.com/h5bp/html5-boilerplate/blob/943968c7c9da05ac7bb3ae9d6127b7d70f2d9f2e/js/plugins.jsThis piece of code may look familiar to those, who used previous versions of HTML5 Boilerplate. The method was removed from plugins.js some time ago.
@paprikkastudio a TypeError? interesting... in node, and ff it works as expected, in chrome and safari there is a typeerror. i think it's when not a bug, then at least bad implementation. but hey! try that:
var f = console.log.bind(console);)
PS: of course this version is nearly the same as the opening tip :D
@greelgorke Yeah, I agree in 100%, that's really, really annoying when you work in node inspector and developer tools at the same time:)
Regarding fn.bind - I don't know why I didn't think of that! That'a a lot better solution, however you have to remember that IE8 even with developer tools enabled will throw an error, since it doesn't support ES5 bind method.
That's why I prefer typing log + [TAB] in my editor and just polyfill console.log in situations it's disabled (but that's another topic, of course).
@paprikkastudio IE8 is a different beast. i'm all for snippeting too. <3 sublime for it
Bear in mind that this could prevent some JS minifiers from properly removing debugging / console statements when this option is available, as most of them will remove console.xxxx calls only.
