What can JavaScript do?
• JavaScript gives HTML designers a programming tool - HTML authors
are normally not programmers, but JavaScript is a scripting language with a
very simple syntax! Almost anyone can put small "snippets" of code into their
HTML pages
• JavaScript can react to events - A JavaScript can be set to execute when
something happens, like when a page has finished loading or when a user clicks
on an HTML element
• JavaScript can read and write HTML elements - A JavaScript can read and
change the content of an HTML element
