 The [javafx.animation](javafxdoc:AnimationPackageSummary) package offers a simple framework for creating animations and transitions in a JavaFX application.
-It operates on the principle of [`WritableValue\<T\>`](javafxdoc:WritableValue), which is used across JavaFX. `WritableValue<T>` is an interface that wraps a value that can be read and set.
+It operates on the principle of [`WritableValue<T>`](javafxdoc:WritableValue), which is used across JavaFX. `WritableValue<T>` is an interface that wraps a value that can be read and set.
 It is commonly used for storing properties in JavaFX UI elements, like `width` or `height` in the [`Rectangle`](javafxdoc:Rectangle) shape.
 It additionally provides a variety of built-in transitions for common effects, support for parallel and sequential transitions, and the ability to handle events upon animation completion.
 The article goes through all types of animations, starting with `Animation` and its subclasses `Transition` and `Timeline`, before representing a lower level animation with `AnimationTimer`.
