Google is planning to implement Pointer Events application programming interface (API) in Blink, enhancing the scrolling performance in the Chrome browser.
Microsoft first introduced Pointer Events in its Internet Explorer browser. Google has until now supported the Touch Events standard, which is used by Apple in its Safari browser.
Pointer Events have several technical advantages when compared to Touch Events and Mouse Events. Pointer event listeners never block scrolling, replacing all touch event handlers, which addresses the main longstanding source of scroll-start jank that is seen on Android.
Google’s decision to implement the Pointer Events came after a positive feedback from the web community.
Representatives from the Chromium project said: "Last year we announced that, despite our involvement in the Pointer Events standard, we were going to focus on incremental improvements to existing APIs (like Touch Events), rather than implement Pointer Events in Chromium.
"Since then we’ve received a steady stream of feedback from web developers, framework authors, and other browser vendors indicating that they see Pointer Events as a highly valuable addition to the platform.
"Since we’re committed to a web platform which evolves collaboratively through open discussion and data from real-world development, we need to take this feedback very seriously."
