The List for Web Designers

JavaScript tends to scare beginning web designers off due to it being more complex than the simple markup language they’re likely more familiar with (HTML). However, JavaScript does play an instrumental part in making modern websites, and especially web applications. JavaScript enhances the user experience through asynchronous, real-time updating of web pages when an event is triggered (such as a click) through a technique collectively known as Ajax. JavaScript also provides slick interactivity and smooth effects that, by design, is aimed to improve interaction tasks.

JS frameworks like jQuery aid agile development.

JavaScript does have its limits (and for a good reason, as it could be used to exploit vulnerabilities in a user’s computer) and it may not always be available on a user’s browser because it can be disabled. Just like Flash, the best practice for JavaScript is that a web page should be usable and accessible without JavaScript.
