A study on Visual Programming Extension of JavaScript

Abstract

Visual programming extension of JavaScript language is presented and discussed. The aim of designing this language is to make programming simple, easy and more understandable to the audience who are fresh or new in programming, to improve the correctness with which people perform programming tasks, and/or to improve the speed with which people perform programming tasks. It provides ease to programmers, i.e. they are not required to learn or remember syntax. They will just have to enter the values using visual constructs. It is an attempt to make programming and maintenance of programs easier, and therefore cheaper. A hybrid technique is used to design VPxJavaScript, both symbols and text will be used to construct a program using this language. While deciding symbols to be used in, it was kept in mind that symbols must be as few as possible and most understandable shapes have been selected to represent corresponding constructs of JavaScript. The above aspect helped us in designing visual programming in order to keep the language more readable, understandable and writable. This paper highlights the usefulness of each symbol and discusses visual representation of normal JavaScript code. This paper also discussed the problems in JavaScript and proposed solution of problem and its equivalent visual representation.
