Better usage of console.log

No one likes to remove console.log from source after finished development but there’s a good solution for this. We have to set global variable and use custom wrapper function for console.log.

var debug = true,
    _log = function() {
        debug && window.console && console.log.apply(console, arguments);
    };

From now we can use _log function to log messages in console.

_log('Yup, this is good.');
