Web Developer Interview Questions and Answers

Web development is also known as website development. Web development broadly refers to the tasks associated with developing websites for hosting via internet. The web development process includes web design, web content development, client-side or server-side scripting and network security configuration, among other tasks. HTML and CSS are the two most basic web development languages, and are used to build nearly all webpages on the Internet.

Web development can be divided into three parts: Client-side coding, 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 coding, 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.

There are typically eight key skills you would need to become a Web Developer: Communication: Clear communication with clients, as well as the members of your development team, is a crucial skill to have in the industry. Design: Although not necessary, some knowledge of design and layout aesthetics will help you become a prominent developer. Patience: Web Development is a detail-oriented field, and mistakes happen. Patience is necessary to cope with the pressures of the job. Project Management: When designing a website, there are a lot of moving parts, so you need to be able to manage your project effectively, so no task gets forgotten or overlooked. Flexible Working Strategies: Depending on the project, you’ll need to be flexible because you could be assigned to work individually or with a larger group of developers. Mobile Support: It is important that you create websites that will be accessible and functional on a variety of devices. Be Meticulous: To launch a high performing website, you should test your site and make sure that every detail performs as intended. Logical Problem Solving: Any problem a website encounters is an outgrowth of its code. So you should be able to think critically and logically to find the issue efficiently.

Front-end development is also called Client side Development or Scripting. Front end development manages everything that users visually see first in their browser or application. Front end developers are responsible for the look and feel of a site. Client-side scripting which includes HTML, CSS and Java script is any code that runs within a web browser. This means that the web browser temporarily downloads all the files from a web server and, in turn, displays a static web page; you would be able to view these files even if you lost your Internet connection (as long as you left your web browser open). JavaScript most commonly used client-side scripts. In addition to fluency in these languages, front-end developer need to be familiar with frameworks like Bootstrap, Foundation, Backbone, AngularJS, and EmberJS, which ensure great-looking content no matter the device, and libraries like jQuery and LESS, which package code into a more useful, time-saving form. Some examples of client-side scripting languages: • HTML/HTML5 • CSS/CSS3 • JavaScript • Flash • JQuery • Microsoft Silverlight HTML/HTML5: As a fundamental for all coding, HTML acts as a base for building upon all other developer languages. CSS/CSS3: Fluency in CSS allows you to mediate between an app and the design of a site. JavaScript: JavaScript determines how a web page will function and the way users will experience a page. Flash: Flash, a popular authoring software developed by Macromedia, is used to create vector graphics-based animation programs with full-screen navigation interfaces, graphic illustrations, and simple interactivity in an antialiased, resizable file format that is small enough to stream across a normal modem connection. JQuery: jQuery is not a language but a well-written JavaScript code. It is nothing but a small, mostly used JavaScript library. JQuery is very well written compact JavaScript code which increases the productivity of developer and enables them to handle critical UI functionality in websites by writing a very small amount of code. Microsoft Silverlight: Microsoft Silverlight is a multimedia framework for designing rich web applications with graphics and video. It uses a plug-in for several browsers, including Internet Explorer.

Backend Development is also called Server side development or Scripting .Back end development refers to the server side of an application and everything that communicates between the database and the browser. 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. Many back end developers know front end languages such as HTML and CSS but need to use languages such as Java, PHP, and c #, Ruby on Rails, Python, and .Net to get the back end job done. Back end developers are most focused on a site’s responsiveness and speed. Some examples of server-side scripting languages: • Java • PHP • Python • Ruby on rails • ASP.NET • C# Java: Java is the server-side language of choice for large-scale websites with a high volume of traffic. One potential reason for its popularity among high traffic websites is that Java frameworks outperform other language frameworks in raw speed benchmark tests. That means faster server-based web applications for large scale websites. Java Servlets, JSP and WebObjects are examples of server-side solutions that use Java. PHP: This open-source language powers over 2 million websites across the world. The chief advantages of PHP are that it is open source, with a huge online community to support it, and that it’s compatible across multiple platforms. PHP is most often used by websites with lower traffic demands. Python: Python is a high-level, interpreted, interactive and object-oriented scripting language. Python is designed to be highly readable. Ruby: Ruby is used for both desktops and mobile phones, and the Ruby on Rails development framework is one of the most frequently used on the Internet. ASP.NET: ASP.NET is an open source web framework for building modern web apps and services with .NET. ASP.NET creates websites based on HTML5, CSS, and JavaScript that are simple, fast, and can scale to millions of users. C#: This programming language is simple and safe, which explains why it is still one of the most popular languages used today.
