Web workers and its API: Run intensive tasks in the background

In some situations where javascript has to run big loops, the browser may prompt error messages. The situation explained above can be handled using Web Workers, who will do all the computationally expensive tasks without interrupting the user interface and typically run on separate threads.

Page Visibility API: Know when a user is on your page

it was impossible for developers to specify the code that can be executed under any case of unloading a page. In order to solve this problem, Page Visibility API was introduced. The API will listen to any visible change of the page under all the cases, regardless of that, it's on phone or desktop.

Working with Clipboard API and events in HTML

The Clipboard API provides a way to hook into the common clipboard operations of cutting, copying and pasting so that web application can adjust the clipboard data as required. There are two ways we can interact with the system clipboard Document.execCommand() and asynchronous Clipboard API

Working with images in HTML

Images can be inserted into our HTML page using tag. The tag is an empty tag, which means that it does not have a closing tag. We can insert parameters of the element using various attributes like src, alt, height and width.

Working with history object of HTML DOM

The browsers history is present in the history object. We can use the window part (window.history) or just simply history. It contains an array of URLs or links visited by the user.
