Comparative Analysis Of JavaScript And WebAssembly In The Browser Environment

As World Wide Web is evolving, larger and high-performance applications are being entirely run on the browsers. Web applications have their own advantages like they are more accessible and platform independent. JavaScript was the only programming-language which was historically supported to be ran on the web browsers, but it is quite limited to high-performance applications as it is dynamically-typed and interpreted language. So, as the high-performance applications started to come to web there have been always a need for another language which could run in the browser environment but also take advantage of system resources. WebAssembly was one such effort by the vendors of different browsers coming together. WebAssembly is claimed to be portable and size and time efficient binary format which could be compiled to run on the web browsers at near native speed. This paper will try to verify the claim by running various experiments on both WebAssembly and JavaScript and measuring resource used and time taken by those programs to execute and will later do a comparative analysis between the both.
