    Apple has long drawn out its efforts in the field of web development by just releasing the latest version of the Safari web browser. It is explicitly designed and specifically intended to help web developers in their development processes. It's known as ‘Safari Technology Preview’ web browser which enables web developers to acquire an early look at upcoming latest web technologies such as cutting-edge layout technologies, visual effects, different tools of development & many more.

    Apple is planning to implement this in OS-X and iOS to facilitate developers to perform different experiments on new technology. As a result, Apple will get quick feedback and come to know earlier what changes are necessary to deliver more precious outcomes.

    Safari Technology Preview can run beside the currently existed Safari browser. It also provides the ability to developers to set it as the default browser of their machine. It comprises storage of localized data for the concerns of bookmarks, history, cache, and cookies. Synchronization of browsing history, as well as bookmarks on iCloud, is also supported by the browser.

    If we talk about the icon of Safari Technology Preview, it is designed to resemble the Safari icon but it is in purple shading rather than blue. It helps to differentiate from the shipping version. The existing form of Safari technology Preview contains a few JavaScript upgrades, improvements in HTML, and changes in Web Inspector.

    • ECMAScript 6 support lexical scoping, arrow functions, generators, iterators, default parameter values, and a number of new built-in APIs
    • Superior standards-compliant IndexedDB support with additional strength
    • Added the B3 JavaScript JIT compiler with low-latency as well as high-throughput that improves performance
    • Included the capability to utilize document.execCommand('copy') and document.execCommand('cut') in response to a user gesture to copy and cut text programmatically

    Improvements in HTML

    Apple already has Nightly builds of WebKit- the open-source browser engine which runs on a number of devices as well as empowers Apple’s Safari. However, accessing these builds requires a bit more effort than making use of the new Browser. As an alternative, with a new one, upgrades are shared every two weeks by means of the mechanism ‘Mac App Store software update’. It implies that there are fewer hurdles to run a browser which features cutting-edge technologies in the matter of web development including HTML, CSS, JavaScript as well as Web-Kit.
    Developers are also interested to come across what is coming out with the latest version. This includes a variety of first-release features like,

    • ECMAScript 6
    • Updated Indexed DB Implementation

    • B3 JIT JavaScript Compiler
    • Support for programmatic cut and copy to the clipboard

    Safari Technology Preview is present on the Apple developer website. It will obtain regular updates through the Mac. There is no necessity to register yourself as a developer to download the version. Apple is also inspiring web developers to make use of Bug Reporter to give comments about Safari technology previews to tell them what is working and what is needed to be improved.

    Amazing features:

    • Run side-by-side with safari
    • Offer response and feedback
    • Preview the latest web technologies
    • Access powerful developer tools
    • Surfing flawlessly with iCloud
