How to use JavaScript?

There are two main types of JavaScript: scripting language for creating applications that run on the client side, and compiled – for server-side programs. The latter exists only within the product Netscape LiveWire. We will focus on the first type, which is mostly popular among Web users. The client version of JavaScript is simply a set of instructions designed to be embedded into HTML-pages, as a rule, between the tags <SCRIPT LANGUAGE = “JavaScript”> and </ SCRIPT>.

JavaScript-commands are placed in HTML files, mainly in three areas: in the tags <HEAD> and <BODY>, as well as in the tags of specific form elements. When a page with embedded JavaScript-commands loads into the browser supporting this language, these commands are interpreted and executed line by line.

For those who used languages like C, the relatively simple JavaScript syntax should look familiar to them. The hardest thing in the application of JavaScript is to understand that the whole set of objects displayed in the browser window (windows, frames, forms, lists, etc.) can be controlled from a JavaScript-scenario using the appropriate object links.

Furthermore, JavaScript has built-in functions or methods that can be applied to objects during the standard types of work with them. Let’s suppose you need to create a small notification window. This can be done with the help of the window object, using the command window.alert (“Hello World”). After applying, a window with the text “Hello World” appears in it.

In general JavaScript language is rich in various features and methods, and you can really master them if you have a more profound understanding of all available opportunities. In fact JavaScript  is very clear and procedural, similar to most other programming languages.
