Are you aware of the capabilities of JavaScript programmes? Here's the answer: today we'll go over all of [JavaScript features](https://www.calltutors.com/blog/javascript-features/) in detail. JavaScript does have certain unique characteristics that contribute to its popularity. Today, practically every website employs Javascript, making it an extremely useful language to learn. The best thing about javascript is that it doesn't require any prior programming skills.

## Overview of Features of JavaScript

The characteristics of JavaScript are described in detail in the following article. Brendan Eich created Javascript in 1995 for scripting on web pages, allowing logical operations to be performed at the client edge. JavaScript is mostly used as a client-side scripting language. This object-centered script language, which was developed in Netscape, is most widely used for developing web pages. It gives the user more control over the browser and allows for the creation of new script functionalities. This scripting language supports case-sensitive input as well as browser and operating system detection. Validation in client edge technology frequently employs JavaScript.

## The following are more characteristics of JavaScript:

1. Object-Centered Script Language
2. Client edge Technology
3. Validation of User’s Input
4. Else and If Statement
5. Interpreter Centered
6. Ability to perform In Built Function
7. Case Sensitive format
8. Light Weight and delicate
9. Statements Looping
10. Handling Events

The Statement Control Syntax System used in Java Script is quite similar to the Statement Control Syntax System used in C. Because HTML is only capable of constructing websites, it is unable to conduct logic operations such as condition checking, looping statements (while & for), statement decision making (else and if) at the client edge, and adding two numbers.

Because JavaScript is unable to perform these functions, we must use JavaScript to do these activities at the client's edge. This scripting language can aid in the development of more interactive websites, as well as the development of inbuilt clocks, light client edge programmes, and the creation of windows popups with various dialogue boxes such as alerting dialogue boxes, confirmation dialogue boxes, and prompt dialogue options.

Nowadays many web-based giants are using the technology of Java Script like Facebook, YouTube, Twitter, Gmail and Google Maps, etc. The Java Script features Enterprise level pop-down menus, Opening, and Closure of new window, manipulation of HTML Layers, Interface Enhancement of HTML, Adding animation essentials within the page, adding dynamic appearance in documents of HTML and Fixing of problems related to Browsers.

JavaScript can be used to validate data input within HTML Form data before it is transmitted to the server. Java Script also allows users to manipulate data for HTML layers such as relocating, hiding, changing the interface of HTML codes, and writing them individually, among other things.

## JavaScript Features

Now let us see the features of JavaScript in detail:
**1. Object-Centered Script Language
**As Javascript contains a window object, Object Centered Language includes built-in functionalities. Javascript and Visual Basic are two examples of object-oriented languages. Polymorphism, which is the ability to take an object in many different forms, is a property of object-centered languages. When representing a reference from a parent class to an object of a child class, we must use polymorphism in object-oriented programming.
**2. Client Edge Technology
**In terms of the user, the client is essentially a phrase used for Web Browsers. A client uploads data to the server, which is then used by a user in the rendered form. The client is accessed by a web browser, which allows the user to surf and interact with websites. Java Script's client edge technology gives clients complete control over the material that is being updated on servers.
**3. Validation of User’s Input
**Form validation, also known as user input validation, allows users to interact with clients by completing forms on web pages. The form's details must be appropriately filled, and form validation assists the client in validating the information submitted by the user.
**4. Else and IF Statement
**To conduct logical operations, IF and Else Statements are employed.

**5. Interpreter Centered
**The user can access the result without using a compiler because Javascript is built with Interpreter Centered. That is, the user's input is represented directly without the need for code compilation.
**6. Ability to Perform In Build Function
**Many built-in functions in Javascript include isNAN (), Number (), parseFloat (), and parseInt (), among others. The isNAN () function determines whether or not the input object is in the right numerical format. The object is converted to an integer using the parseFloat () function. The function parseInt () is used to analyse strings.
**7. Case Sensitive Format
**The output of Javascript codes is Case Sensitive, which means that whether the codes are written in UpperCase or Lowercase Format, the output will be the same.
