Hello Readers , Welcome to yet another insightful blog at CareerHunt.
- Web Development Background
Therefore, I am trying to bring to light here its basic concepts and compare their usage, with a few demonstrations & figures wherever possible & necessary for better grasping.
But first, let us understand what exactly do we mean by “Client side programming”.
2.Web Development Background
Web development is all about communication. In this case, communication between two parties, over the HTTP protocol:
- The Server – This party is responsible for serving pages.
- The Client – This party requests pages from the Server, and displays them to the user. In most cases, the client is a web browser.
- The User – The user uses the Client in order to surf the web, fill in forms, watch videos online, etc.
Each side’s programming refers to the code which runs at the specific machine, the server’s or the client’s.
Server-side programming is the general name for the kinds of programs which are run on the Server.
- Process user input
- Render pages using HTML, etc
- Structure web applications
- Implement business logic of the application
- Interact with permanent storage (SQL, files).
- ASP.NET in C#, C++, or Visual Basic
Nearly any language (C++, C#, Java). Note- These were not designed specifically for the task, but are now often used for application-level web services.
Much like the server-side, Client-side programming is the name for all of the programs which are run on the Client. It has mostly to do with the user interface with which the user interacts.
- Make interactive webpages.
- Make stuff happen dynamically on the web page
- Interact with temporary storage as well as local storage (cookies etc.)
- Send requests to the server, and retrieve data from it, provide a remote service for client-side applications such as software registration, content delivery, remote multi-player gaming, etc.
- HTML, CSS
Any language running on a client device that interacts with a remote service is a client-side language. However, HTML and CSS aren’t really programming languages. They are markup syntaxes by which the Client renders the page for a User.
Some of the main tasks of Client-side programming include-
- Validating input :Validation must be done in the server. A redundant validation in the client could be used to avoid server calls when speed is very critical.
- Animation & graphics
- Manipulating UI elements
- Applying styles, etc.
It is designed for building network-centric dynamic web pages and web applications.
However, its understanding & implementation gets quicker & easier if the reader has some prior exposure to object-oriented programming concepts and a general idea on creating online applications.

It means that a web page need not be a static HTML, but can include programs that interact with the user, control the browser, and dynamically create HTML content.
- Executed on the client side. For example, we can validate any user input before sending a request to the server. This reduces the load on the server.
- A relatively easier language. It’s quite easy to learn and the syntax is close to general English.
- Provides an instant response to the visitors. That is, no server interaction is required, hence we don’t have to wait for a page reload to obtain the desired result.
- Eases creating interfaces that can react when the user hovers over them or activates them using the keyboard, thus increasing interactivity.
- Provides rich interfaces. Drag and drop components or sliders may give a rich interface to our site/application.
- Doesn’t implement any multiprocessor or multi-threading capabilities.
- Doesn’t allow us to read or write files.
- Rendering may vary across different layout engines. As a result, this causes inconsistency in terms of interface and functionality.
Since it is an interpreted language inside the context of a web browser, we don’t even need to buy a compiler.
These tools offer capabilities ranging from event-handling to code reduction and data-rendering.
VS Code (Visual Studio Code)
It is an online community for creating, collaborating on and sharing our web development ideas. Plunker is great for prototyping test ideas. Here’s a sneak peek into how it looks-
Chrome’s dev tools
It is an open source text editor for building super rich & responsive applications. It is a modern text editor. Here’s a sneak peek into how it looks-
|Client-side v/s Server-side
||HTML is rendered from the server on the browser. This means that any (Backend ) code programmed on the Web page is processed by the server before it is sent to the user.
||HTML is a static markup language in which we can’t do anything dynamic just by using its tags. The static code created in the HTML pages are hosted on the website’s domain and the HTML rendered can be created using dynamic programming languages such as C#, PHP or VB.NET.
||Consistently supported by all browsers, and the main tags used for a Web page are rendered without an issue
- Allows us to create highly responsive interfaces that improve the user experience and provide dynamic functionality, without having to wait for the server to react and show another page.
- Information that changes constantly can be loaded periodically without the need for user interaction. For example, sports match results, stock market tickers, etc.
- Can be used to animate elements on a page. For example, to show and hide information, or highlight specific sections of a page. This can vouch for a more usable, richer user experience.
- Works on web users’ computers, even when they are offline.
- Can test for what is possible in our browser and react accordingly. This phenomenon is commonly known as defensive scripting.
We at CareerHunt researched & surveyed a few tech communities & forums to get a hunch on the developer skills in order to ensure that we can provide our readers with the crux of what’s cooking in the tech market, such as, when did they push code for the first time, how do they learn coding, what are their favourite languages and frameworks, what do they want in a job, what hiring managers want in a candidate, etc. One such source for this particular research is HackerRank.
Most often, employers want developers who know AngularJS, Node.js, and React.js.
React.js has the biggest margin between percentage of developers who know the framework and percentage of employers who look for candidates with this skillset. In other words, there’s a big opportunity for developers to learn React as a marketable skill that companies need today.
