In all these years, developing the client-side portion of web applications has changed dramatically. And these challenges are chiefly related to technologies. With the changing nature of the technological landscape, it has become exceedingly difficult, yet important, to note these alterations and modify them.

So here, in this post, lies an opportunity for the readers and the industrial leaders to rethink about what is known about all these challenges. Each of these technological challenges modifies as per the business and as per the transformations that govern today’s technological environment. So here are the challenges, which, if not adapted to, will become roadblocks to progress.

Technological challenges

Evolution

JavaScript along with the associated standards was out of expediency some two decades ago. In earlier times, JavaScript was never viewed as a premium language. It was simply apt to render a couple of simple animations or to do form validation, but it was never perceived as a platform that could do cutting-edge web application development.

However, JavaScript received a lot of attention from developers and business people in the past few years. That is because JavaScript has advanced for:

• Keeping up with the ever-changing technological landscape.
• Receiving key features from different languages. This specifically has enabled the programming platform to introduce new toolkits, frameworks, and libraries

The biggest technological challenge for developers is that they have to battle with these changes and manage environments where the foundation is always shifting. Sometimes, it is so exhilarating to view each of such changes; while at other times, it is downright frustrating to see that a lot of changes have been implemented and a lot many are still waiting to be deployed.

Complexity

The different capabilities of web apps are pretty simple. However, today, a web app may comprise close to hundreds of technologies and approaches—now, this is something that the developers of full-stack, large applications will agree.

Understanding the programming languages and the available APIs is not enough today. Rather, the developers will have to understand a range of different elements (which will play a critical role in shaping the web applications). These elements are:

• Network performance
• Rendering engines
• A variety of fresh and emerging techniques and technologies

Testability

Testing an app source code is often easier said than done—and the testing becomes pure pain whenever the application sections are never easily separable. (The code that is simple to test, maintain, and reuse is really valuable for any developer.)

During the testing phase, the error, reported within an application, usually manifests itself within the front end. Because of this, the errors are nearly always reported against the JavaScript development team. So having assurance about front-end codes will always make it simpler and quicker to identify issues and isolate them anywhere else within the application. Also, as there are more and more cutting-edge devices and diverse platforms, the simplicity with which automated testing can be carried out in this platform is simply astounding.

Measuring the quality

There have been countless ways with which the quality of a codebase can be measured. These ways generally include code performance, standards, documentation, consistency, efficiency, comprehension, and test coverage.

The biggest quality-related challenges which countless organizations agree with are on a specific set of metrics. After agreeing, the testing team will have to stick with these standards. The key value of measuring quality is for gaining precious confidence that is needed while executing a set of web applications. These fix testing standards even enable the team of testers to maintain these web apps easily and quickly.

Selecting the development tools

As the ecosystem is growing and becoming more and more robust, there is a range of solutions to different problems. These challenges can be determined by deploying different solutions. It has been witnessed that the demos and examples of a set of technologies and tools oversimplify the use case. For this purpose, a lot of deployed tools and technologies do not really answer any critical questions. For this reason, it becomes even more challenging to measure how an underlying technology will perform and deliver during constraints and with different project requirements.
