A widget is a tiny yet very important feature or tool that is embedded into a website or an application to provide a specific function or to display a piece of content. Some examples of content can be search bars, social media feeds, chatbots, and even calendars.
Widgets are very important because they improve the user experience of the website or the application by adding features that are useful. These are available at just one click, so the users do not have to navigate a lot. They make the website dynamic.
