A web developer is a programmer who is specialized in the development of World Wide Web applications & distributed network applications which are run over HTTP from a web server to a web browser.


As the web technology is very much popular nowadays and provides advanced features, it is become an essential part of every business to have a website. These websites should also be highly functional and visually attractive. The process by which a good internet site, mobile apps or other similar platforms are created is known as web development. One of the most vital parts of web development is web programming which is achieved with the help of programming languages. Web development languages are the platforms by which instructions are communicated to a machine and actions are followed.


Web development is a term which is used to refer the process of creating a website. It can range from developing a simple single page to various complex pages. Web development covers various actions & practices, some of them are – web design, programming, content creation, network security tasks, client side & server side scripting, etc. In the recent few years, web development has taken the definition of the creation of CMS. CMS is the mid-step between the user and the database. A web developer should be expertise in programming languages.


A programming language is a language which is used to control the actions of a machine. A programming language is properly drafted & constructed language. It is designed in such a way that through it instructions can be communicated to a computer system. From the invention of computers, thousands of programming languages have been created. Not only this, every year new programming language is being created.
A programming language can be divided into two components that are – semantics and syntax. A syntax is a form or type whereas semantics is the meaning of that type or form. Every programming language is different from each other & have different feature. Some may be marked by a specification document whereas others may have a dominant reference or implementation. Thus a programming language mainly a notation which helps to write programs which are identified as an algorithm.


There are various features of a programming language. The three most important features of programming languages are – Abstractions, Function, and target & Expressive power.


As there are various programming languages, it becomes a difficult task to select which one to use and which one to leave for a web developer. However, there are certain factors on the basis of those factors decision can be made. Those factors are – language domain match, targeted platform, elasticity and performance, efficiency, project size, availability of libraries, time to production, expressiveness, tool support and much more.


The universe of programming languages is wide so learning each one of them is neither possible nor practical. JavaScript is the most popular programming language nowadays. It is followed closely by Java, Python, Ruby, PHP, and others.
