People often see passwords are the original sin of authentication on the web. Passwords can be easy to guess and vulnerable to breaches. Frequent reuse of the same password across the web makes breaches even more profitable. As passwords are made stronger and unique, they can quickly become unusable for many users. Passwords indeed look notorious, but are passwords themselves the problem, or is it

On June 23rd, the WebKit project froze its Subversion tree and transitioned management and interaction with our source code to git on GitHub. Why git? git’s distributed nature makes it easy for not just multiple developers, but multiple organizations to collaborate on a single project. git’s local record of changes makes moving commits between branches or reverting changes simple and quick. git’s

We’re pleased to announce that Safari 11.1 on macOS and Safari on iOS 11.3 now support the W3C Payment Request API for conducting Apple Pay transactions on the web. We first introduced Apple Pay on the Web in macOS Sierra and iOS 10. Apple Pay brought novel ease-of-use, security, and privacy to online transactions, so we’ve been encouraged to see it widely adopted by merchants in the years since.

With the recent addition of SharedArrayBuffer, concurrency is finding its way into the JavaScript language. This addition allows JavaScript programs to perform concurrent access to SharedArrayBuffer objects. WebKit supports SharedArrayBuffer and it has full optimization support in our compiler pipeline. Unfortunately, JavaScript does not allow any objects other than SharedArrayBuffer to be shared.

As of r195562, WebKit’s FTL JIT (Faster Than Light Just In Time compiler) now uses a new backend on OS X. The Bare Bones Backend, or B3 for short, replaces LLVM as the low-level optimizer in the FTL JIT. While LLVM is an excellent optimizer, it isn’t specifically designed for the optimization challenges of dynamic languages like JavaScript. We felt that we could get a bigger speed-up if we combine

It simulates user interactions in web applications, using TodoMVC to orchestrate adding, completing, and removing todo items. Speedometer repeats these actions using DOM APIs that were extensively used in real-world applications.

Web authors often need to know when a particular element on a page becomes visible. The element could be an ad or a video whose viewability we want to compute. Or we might want to defer loading an image until it is visible. A common way to solve this problem is using polling, periodically computing the position of an element with respect to the viewport. However, polling is inefficient, wastes bat
