It offers a convenient unified model for programmatic animations, CSS Animations and Transitions.

It provides access to the system clipboard and clipboard operations while keeping the webpage responsive. This API is much more flexible than DataTransfer, allowing developers to write multiple items with multiple types per item. Additionally, it brings programmatic paste to all websites on macOS and iOS. The implementation is available through the navigator.clipboard API which must be called within user gesture event handlers like pointerdown or pointerup, and only works for content served in a secure context (e.g. Instead of a permissions-based model for reading from the clipboard, a native UI is displayed when the page calls into the clipboard API the clipboard can only be accessed if the user then explicitly interacts with the platform UI.įor more details see the original API specifications. These releases include new JavaScript support for the replaceAll() method for strings and the new nullish coalescing operator ( ?). The () method does exactly what it suggests, replacing all occurrences of a given value in the string with a replacement string. The nullish coalesing operator ( ?) is a new operator that only evaluates and returns the expression on the right of the ? if the result of the expression on the left of the ? is null or undefined. const nullValue = null Ĭonst resultWithNull = nullValue ? "default" // "default"Ĭonst resultWithNonNull = nonNullValue ? "default" // 0įor more details see the Nullish Coalescing for JavaScript proposal. The addition of ResizeObserver in WebKit enables developers to design components that are responsive to the container instead of just the viewport. This allows more flexible responsive designs, where containers can react to window size changes, orientation changes, and additions of new elements to the layout. The JavaScript API avoids the circular dependencies of trying to use media queries for element sizes in CSS. #APPLE IOS WEBKIT APP INFREQUENTLYNOTED MANUAL#.
