Web Developer Q/NA Series — 2 | Talent-House {Latest 2021}

Web Developer Q/NA Series — 2 is our second series with exclusive questions with deep answers, read this article and learn more///

We have come again with a lot of question-answers but we will cover only 6 questions today. So I think we need to start.

Do people use C++ for web development?

The primary advantage of C++ and the rationale behind so much of the work you do when writing it is performance. An HTTP server interface is the textbook example of an application with little opportunity to benefit from this.

Why?

1. When a user makes a web request and loads a page, the great majority of computational operations involved are already being executed by performance optimized machine code, even if a little bit of work is done by some slow language like ruby. I’m talking about the web server that handles the TCP protocol, the app server which parcels requests into worker queues, the parser which deserializes requests, the serializer to do the reverse, the database engine to fetch/manipulate data, the browser to render markup and act on javascript. All of these are optimized libraries written in C or C++.
   A well-designed web app backend will aim to have its key business logic expressed in meaningful but minimal, computationally trivial glue between these components.
2. Network latency. From a UX perspective there is little difference between a well written ruby server and a well written C++ one. This is because the irreduceable factor is the time taken to establish a network connection and get a response from the far-away server.
3. The nature of client-server architecture where the client is a human operator. An individual person has an extremely low data bandwidth compared to a computer. The amount of meaningful information they can receive or send in text form is limited. That’s the reason that for each user interaction it should nearly always be possible to ensure that the amount of raw data that *must* be processed immediately is low. That is why the “overhead” factors mentioned in point 1 tend to dominate on each web request.

All this said, this is the theory of why fast languages aren’t necessary for a web server. In practice, companies find themselves often struggling to keep reliably fast responses, because of edge-cases, requests that are most practical to process in a naive way, or maybe the scope of the HTTP server starts to creep into being not just the *interface* for a large scale business system, but the system itself.

If this happens, then even if you succeed in maintaining a decent subjective user experience, if you have loads of users then you stand to save a lot of money on servers by switching language.

So there are decent reasons that companies may decide ruby or python aren’t fast enough for them (although they more often decide the problem is the lack of type-safety). Still, at that point, whilst C++ is the fastest, Go, C# and the JVM languages aren’t far behind while being far better suited to the job.

Is web developer a good career in 2021? What is the future for web developers?

Web Development is the process of building, creating, and developing websites or web applications. It’s one of the popular fields in the tech industry. Web development encompasses all the actions, updates, and operations required to build, maintain, and manage a website to ensure its performance, user interface, user experience, and speed are optimal. These days Web Development became more complex due to the number of web technologies and tools needed, also because of the modern web that needs a lot of requirements today. that’s why we see new roles such as Front-End, Back-End, and DevOps.

As you can see the Average Web Developer Salary in 2020 is about 60k$ per year. It also depends on the company you are working for. Salaries for Web Development jobs are increasing year after year. That means Web Developers are in high demand at the job market in 2021.

WordPress & Wix VS Web Development :

irstly, let’s talk about WordPress and Wix. WordPress is a CMS or Content Management System which means that you can manage the content of your website without knowing how to code, you can also add themes for your Website. On the Other hand, we have Wix which is a website builder that creates a website for you, so you don’t have to know how to code. they seem similar, but WordPress has a lot more features than Wix, but the problem here is that some people think that WordPress and Wix are going to take the place of Web Development, and that’s not true, because of the following reasons :

1. Web Development gives you more Freedom on your projects.

2. You can’t build custom projects with Wix or WordPress if you don’t know Web Development.

3. You will need to Know Web Development for larger websites and applications.

Why is Learning Web Development in 2021 Worth It?

First of all, web development is never going to go out of fashion, at least after 10 years. True, services like WordPress and Wix have come a long way and one can easily design and create a simple website using these. but quality web developers are always going to be required who can turn some great business ideas into reality from scratch.

The worth of your time and effort put into learning web development will depend on what and how deeply you are going to learn. Surely, you will start with basic HTML, CSS, and JavaScript.

But nowadays, web development has moved way beyond basic HTML, CSS, and JS. Websites are getting more complex day by day and for developing and maintaining such scalable applications, you should have good knowledge about modern frameworks and technologies that are constantly evolving like: Vue Laravel ASP(dot)net, etc. with new versions coming out every six months.

Also, if you want to get started and land a job in a quick time, you should know what the current requirements of the industry are. For example, nowadays MERN or MEAN stack developers are high in demand as a lot of websites are built using these. So you have to work hard as well as smart.

Conclusion:

So in the end, yes, learning web development is totally worth it only if you are passionate about it and don’t run away from learning new things every day.

What web development programming language is Shopify written on?

(1) Shopify was built with Ruby on Rails.
(2) PHP are also used in Shopify.Shopify is based on Ruby on Rails , they are using Rails as their framework and Ruby as their main language

Liquid is an open-source template language created by Shopify and written in Ruby. It is the backbone of Shopify themes and is used to load dynamic content on storefronts. Liquid has been in production use at Shopify since 2006 and is now used by many other hosted web applications.

Do web developers copy and paste?

I very rarely do, when I do web development, which is also rarely; so I guess I “rarely rarely” do it.

I type fast enough that it’s usually easier to just write small chunks of code out again, and that avoids introducing security flaws, which are pretty easy to cause, if you are using copy/paste code.

For very large things, I’m probably going to read them in one Terminal window, and rewrite them in another Terminal window, as I understand what they are doing. This also avoids introducing security flaws in the final product, through non-comprehension of exactly what the code is doing, or exactly how it works.

Yes, that means I tend to do web design — unless we are talking a layout, in which case, yes, that’s WYSIWIG editing — in “vi”, rather than in an IDE.
