JavaScript
Firstly, JavaScript is not Java. JavaScript is a scripting language developed by Netscape, it carries with it a small command set and a simple structure, though it remains an OOP (Object Oriented Programming Language). OOP can make a language easier to tackle, by breaking a program up into 'parts' to make up the whole.

Something important to note is that JavaScript is unable to stand on its own. It is a text-based language that must be placed within HTML, to be read by the browser and interpreted so the instructions can be performed. Because of this, JavaScript is also easy to edit: simply alter the text, and re-run the HTML. For simple applications, this is ideal; for complex applications, this is limiting. JavaScript is geared entirely towards web-development while Java, because of its amazing versatility, is geared to almost any use you have in mind.

I use JavaScript extensively for client-side validation, for example checking user input into an HTML form, providing feedback and assistance.
