Preventing console.log issues in IE

In some older browsers, including versions of Internet Explorer, window.console doesn’t exist and therefore calling console.log() will result in an error.

One way of fixing this is to create a function which checks whether console exists and use this function instead:

function consolelog(v){
    if (window.console
        && window.console.log){
        window.console.log(v);
    }
}

However this requires all developers knowing about this function, and if someone forgets and directly calls console.log() then older browsers will still throw an error.

Therefore a better solution is to check whether console.log() exists, and if not, create an empty function which prevents the error occurring.

if (!(window.console
    && window.console.log)){
    window.console = {
        log:function(v){return;}
    }
}

Alternatively a better shorthand method would be:

window.console = window.console || {log:function(a){}};
