3. What is WIDGET(WIndow gaDGET)?
It's a small, tricky tool that's made especially useful for a job.
A widget is an element of a graphical user interface (GUI) that displays information or provides a specific way for a user to
interact with the operating system or an application.
Widgets include icons, pull-down menus, buttons, selection boxes, progress indicators, on-off checkmarks, scroll bars,
windows, window edges (that let you resize the window), toggle buttons, form, and many other devices for displaying
information and for inviting, accepting, and responding to user actions.

6. Advantages
Client-side scripts offer numerous advantages, including:
Allow for more interactivity by immediately responding to users' actions
Execute quickly because they don't require a trip to the server
May improve the usability of Web sites for users whose browsers support scripts
Can give developers more control over the look and behavior of their Web widgets (note that this can be an advantage or
disadvantage)

7. Disadvantages
Client-side scripts also create additional worries, including:
Not all browsers support scripts, therefore, users might experience errors if no alternatives have been provided
Different browsers and browser versions support scripts differently, thus more quality assurance testing is required
More development time and effort might be required (if the scripts are not already available through other resources)
Developers have more control over the look and behavior of their Web widgets; however, usability problems can arise if a
Web widget looks like a standard control but behaves differently or vice-versa
