The Tortoise and the Hare

There is a natural tension on the web with respect to browser engines. Every engine has their own set of priorities which define the level of investment that they choose to make and on which areas they choose to make it.

A developer naturally wants their experiences to be available to the widest audience possible and these differing priorities create an unevenness on the platform (a lumpiness) making it harder for developers to build experiences that work everywhere.

This section highlights where browsers are pushing and pulling on the platform.

Sprinters

This table is designed to show which browsers are pushing on the platform the most.

Adding features to quickly is not always desired because developers are unlikely to adopt those features in their sites or apps.

For a given year, if a feature landed in Browser X first, how many days it take on average to be available in Safari on iOS and Firefox. TTA (time to available).

api.Event.currentTarget πŸ“‹Firefox11/9/2004 Safari on iOS6/29/2007962
Internet Explorer: On Internet Explorer 6 through 8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent method. In this model, there is no equivalent to event.currentTarget and this is the global object. One solution to emulate the event.currentTarget feature is to wrap your handler in a function calling the handler using Function.prototype.call with the element as a first argument. This way, this will be the expected value.

Chrome: Earlier versions of Chrome incorrectly return true when a tab is first opened, but it starts reporting the correct connectivity status after the first network event.

Since Firefox 41, on OS X and Windows, the returned values follow the actual network connectivity, unless 'Work offline' mode is selected (where it will always return false).Internet Explorer: in Internet Explorer 8 'online' and 'offline' events are raised on the document.body; under IE 9 they are raised on both document.body and window.Opera: From Opera 11.1 until Opera 12.1, the browser returns true when 'Work Offline' mode is disabled and false when it is enabled, regardless of actual connectivity.Opera Android: From Opera 11.1 until Opera 12.1, the browser returns true when 'Work Offline' mode is disabled and false when it is enabled, regardless of actual connectivity.WebView Android: Can incorrectly return true, see bug 41369933.
