Overview of Javascript

Javascript is a client-side scripting language that allows us to implement complex things on a web page. or we can say Javascript is a scripting language that allows programmers to do complex problems in a simple and efficient manner. Using javascript framework programmers can implement more attractive and efficient web-pages.
[Javascript is a high level platform-independent, object-oriented, client-side scripting language used to develop interactive web pages.]

Features of Javascript:

1. Validating User's Input:

JavaScript is pretty useful while using forms. Javascript has the capability to validate the user's input for errors and also it saves time. If the user leaves a required field empty or maybe you fill something incorrect information, JavaScript checks before sending the data over to the server.

2. Object-Centered Scripting Language:

Javascript have Object Centered Language features, built in the object as Java Script has a window object. The object-centered languages are mostly used for features like Polymorphism. Some Examples of Object Centered languages are JavaScript and Visual Basic etc. 

3. Interpreter:

Java Script is built with Interpreter which allows the user to get the output without the use of any Compiler. That means the input performed by the user gets rendered directly without the compiling of codes.

4. Greater Control:

JavaScript provides greater control to the browser rather than being completely dependent on the web servers. JavaScript provides various browsers with additional functionalities that help reduce server load and network traffic.

5. Case Sensitive:

Javascript allows us to write code in any format i.e upper case or lower case. The codes written in Java Script are Case Sensitive which tells that there will be no difference in the output whether the codes are written in Upper Case or Lower Case Format.

6. Detecting the User’s Browser and OS:

JavaScript is very intelligent in the detection of the user’s browser and Operation system information. Though JavaScript runs on every platform, there may occur a situation where we need the user’s browser before processing. This can be helpful for writing code that results in different outputs in different browsers.

7. Handling Events:

The Java Script has the ability to control operations updated on servers. This is basically controlling the response on the website when the user tries to perform any operation the server handled by the client like clicking on links and options, interaction response over the website, etc.

8. Property Shorthand

Javascript built-in methods like .get() are available for the programmer's use. These methods help avoid writing the same code every time and cut back on various lines of code.
