web developer is a programmer who creates programs and applications for the World Wide Web. A web developer knows how to build a website from the bottom up: they can create custom code to accommodate your unique needs, developing everything from the site layout to features and functions on the webpage.

Web Development can be divided into three parts:

  • Client-side scripting, which is code that executes in a web browser and determines what your customers or clients will see when they land on your website.
  • Server-side scripting, which is code that executes on a web server and powers the behind-the-scenes mechanics of how a website works.
  • Database technology, which also helps keep a website running smoothly.

    Web Developer

    It’s easiest to look at a web developer description by splitting the skills into the three areas mentioned below: client-side languages, server-side languages and database technologies.

    Client-Side Languages

    Client-side scripting refers to the creation of web applications that execute themselves within the browser of a user’s computer, like storing user data in cookies, simple flash games, or other forms of interactive web applications. This also includes using languages like HTML, CSS or JavaScript to build the layout, look and feel of a website.

    Here are some examples of client-side languages:

    • HTML
    • CSS
    • JavaScript
    • Flash
    • JQuery

 

Server-side languages

Server-side scripting is a technique used by web developers to build the backend of a website. Server-side scripting involves constructing the framework that allows the database on the web server to communicate with the web browser of the end user’s computer. To make it work, the developer embeds scripts in your website so that, when someone using your site takes a particular action, the server can display set images or information. Server-side code is also inherently more secure, as the person using your website has no direct access to source code, proprietary databases or data beyond what’s specifically shown to them.

The following are examples of server-side languages:

  • ASP.NET
  • C
  • Java
  • PHP
  • Python
  • Ruby

 

Database technologies

The final set of skills to look for in a web developer is the database technologies they are familiar with. In order to work properly, every website needs a database to store its code, images, files and other data.

These relational database management systems (RDBMS) are the most popular for web-based applications:

  • Oracle
  • Microsoft SQL Server
  • MySQL
