“Scroll Fire” is a directive that enables a method to be called (once and only once) when the user scrolls current page and the DOM element (or component) that it is applied to comes into the viewport.
There is also a Scroll directive which fires whenever user scrolls the page.
For performance purposes, the scroll listener function injected is by default debounced by 50ms.
