Learn about javaScript And Its Types?

Javascript and it,sTypes

Javascripts is a more efficient compute  language. It is less weight and mostly used as a web developing to clients side scripts of cooperate with the user and make forceful pages. It is powerful programming language with object-oriented competences.The code that can make itself, usually written to build a program. There are many parts of javascripts that user code itself to build a program.  All program are  outcome of Javascript. Applet is program. An applet is a small application program built up for using Java. It is only an program but some it can say as a application.Some important examples of javascripts are given below:

Client-side JavaScript

Client side JavaScript is the more important and usual form of the language. The script should be consist in   HTML document for the code to be interpreted by the browser.It show saw that a web page need not be a standing HTML, but can consist of programs that given link  with a user or  control the browser or create HTML content.The JavaScript client-side tool provides many important advantages for traditional Computer Graphic Interface server-side scripts. For example, if you can  use JavaScript to find that the user has entered a valid e-mail address in a form pages.

JavaScript Datatypes

On second most important types is Datatypes. One of the most essential characteristics of a programming language is the packets of data types that it supports. These are the type of values that can be showed and worked in a programming language.JavaScript give you to work with three primitive data types  that are showed as Numbers,Strings ,Boolean. In those primitive data types, JavaScript provisions a composite data types known as object form. These are types can exist in different methods and meanings. There are many JavaScript has dynamic types. It  means we can use same variable can be used as different types. Some examples are given below.

var x;          
var x = 5; 

var x = "GCUF";

String Type

JavaScript's string type can be used for textual data. It is a packet of "elements" of 16-bit unsigned integer values. These elements in the String lay a position in the String. The first element can start by index 0, the next at index 1, and same as all other index. Length of string can checked the elements in string. Some people can unlike in languages like as simple C, JavaScript strings are unassailable. It means once string is created at time and not possible to moderate it. However, it is possible to making another string based on this operation at the original all string. Some original strings form are shown it as “string.substr()”.
