We can use the tel: URL scheme for phone numbers in HTML. Just like the mailto: URL scheme will open the default mail application will the tel: start a telephone call. If the HTML page is viewed on a mobile phone and we select a link with the tel: scheme we can immediately call the number following the scheme. On a desktop computer a VOIP call will be initiated.

Every once in a while I work on a site which has some or copious amounts of javascript. Now I do not mind this at all. But it's pretty tedious stuff writing the code and putting in loggers.

But rather then removing all the logging i've found there's an easy solution. Building yourself a logger like structure which checks the existence of the console before writing. That way you can add logging statements without crashing the entire application. A sample logger would look like this:

logger={
    log: function(message) {
        if(window.console && console.log) console.log(message)
    },
    dir: function(message) {
        if(window.console && console.dir) console.dir(message)
    }
}

// We can call this like so:
logger.log($("head title").text());

// or so:
logger.dir($("body"));
