| Javascript basic information |
***Javascript is a client side scripting language or a browser scripting language. Client Side Scripting Language, its means that the browser will run or execute these scripts. The opposite of the client side scripting language is the server side scripting language, the code for the server side languages is execute or run through the web server.
*** JAVA and Javascript are fully different programming languages.
JAVA is a fully object oriented programming language and Javascript is a scripting language. JavaScript is also a programming language, but it only works in browsers where a completely separate application can be created with JAVA that runs on a PC.
*** Many of Javascript's syntax is specifically taken from JAVA but there is no need to know JAVA or any language in advance to learn Javascript.
*** Javascript is basically made up of 3 things.
- ECMAScript (this is the core part of JavaScript or core functionality).
- DOM (Document Object Model - Works with web page content)
- BOM (Browser Object Model - works with the browser)
*** Javascript can be used to create various effects or interesting things on an HTML page, as well as form validation and Ajax work. The most popular works are :
- Clock
- Mouse Trailers (animation created on a mouse while browsing the site)
- Dropdown menu
- Alert massage
- Popup window
- Form validation
- Slideshow
- Moving news
- So more ...
You must know the HTML well before you start JavaScript.
