From its modest beginnings as a tool to validate forms, JavaScript is now an industrial-strength language used to power online applications such as spreadsheets, IDEs, image editors and even 3D games. Since all modern web browsers support JavaScript, it provides a medium that is both easy to distribute for developers and easy to access for users. This paper provides empirical data to answer the question: Is JavaScript fast enough for numerical computations? By measuring and comparing the runtime performance of benchmarks representative of a wide variety of scientific applications, we show that sequential JavaScript is within a factor of 2 of native code. Parallel code using WebCL shows speed improvements of up to 2.28 over JavaScript for the majority of the benchmarks.

Many of the programmers move towards object oriented programming languages due to its reusability nature, whereas in procedural programming languages reusability is not allowed, which may contribute to the high cost of development. Most of web browsers make use of JavaScript as a user interactive program that is a client side program due to its active nature. In the client side programming it is practiced to enable user interaction, control browser activities and alters the content changes made by user dynamically. On the server side programming language, it is used for desktop and mobile application growth. JavaScript is mainly applied for maturation of object oriented web application development because of its supportability of inheritance via prototyping and also properties and methods. In this work the various object oriented concepts are discussed. The methods and operation supported by the object oriented JavaScript language is likewise talked about. Its nature of operating methods, type refinement of JavaScript language, various access control mechanisms over JavaScript language is discussed. The enabling of transaction control over JavaScript language is also elaborated.
