Final Thoughts: JavaScript App Solutions with TechMagic
Why Choose JavaScript?
JavaScript is a popular language that is applied by almost 95% of all the sites as per a recent W3Techs report. JavaScript App is used as a client-side programming language when you need something more than just static pictures. The features of JavaScript include scripting languages, in-built functions, event handling, and much more. It is a great tool to make important changes. Its popularity goes to the easy model, detection of the user’s browser, and design with less load.
With 2020, the latest versions have come up which makes it much faster. Also, memory consumption is two times less. There are many new JavaScript features and tips that 2020 has brought. Let’s check them out now!
Tip #1: Choose the Right JavaScript Framework & Libraries
One of the best JavaScript frameworks trends of 2020 is to find out the right framework for your website. Following are the types of the framework:
- Angular — supported by Google, Angular.js was redesigned and renamed to Angular in 2016. Angular 9 is the last version delivered in 2020. Now, this is one of the most popular and solid frameworks for huge enterprises. For example, YouTubeTV and NBA.com are using Angular for their sites. TypeScript includes all features that are needed to create large projects.
- Vue.js — this is one of the most exciting JavaScript frameworks 2020 trends. Although it is not backed by important clients, it is one of the most efficient frameworks to be used. Vue.js has been utilized by Ali Baba, Nintendo, and GitLab. Vue has Vuex, great memory allowance, awesome performance, and robust application. Among all the frameworks like React and Angular, Vue.js is the trendsetter that can prove to be beneficial in 2020.
- React — it is the obvious leader in the JavaScript system. The framework applies reactive processes, introducing lots of individual concepts/approaches for frontend development. Each framework has its own benefits and challenges. If you want to find out which frontend solution you should choose, you can check a brief overview and see a more detailed comparison of these three frameworks!
Tip #2: Use Components that Will Be More Autonomous from Framework
Web components are gaining popularity, especially the ones that are maintained by web browsers. Also, Chrome has been supporting web components.
Following are some tips regarding web components:
- Passing data into components — it is advisable to put data via attributes into the components. It is called “presentational components.” Also, if you have complex data to be inserted, it can be done by passing through JSON.
- Custom events — it’s a way to tell us that there are some interesting modifications when the components are not linked to the framework. It is better to leverage for the website, this makes the components framework independent.
Tip #3: Use TypeScript
TypeScript is one of a kind among all the JavaScript technology trends. If you have a big project, it is advisable to use TypeScript as it is definitely the highlight of the software development. The future of TS is bright. It can be used by installing the NPM package (Node Package Manager). Following are the reasons to utilize it:
- TypeScript makes JavaScript more than just a scripting language — lots of impressive languages entered the market in the last decade and one of them is TypeScript. One of the reasons for the TS popularity is that some programming languages aren’t able to take advantage of emerging processes in the hardware, for example, in faster networking or cloud computing solutions. So the TS structural typing system compiles JavaScript.
- State of the art — not only does it make things easy with recognizable coding patterns but it also has state of the art technology. It supports the evolving and emerging JavaScript. Features like ECMAScript 2015, async functions, and decorators might prove to be helpful JavaScript technologies in 2020.
- Quicker and simpler development — TS is a modern language that is mainly focused on Ergonomics development (minimizing system fatigue).
Tip #4: Meet the Latest Features
If you are interested in using JavaScript in your future projects, you need to keep up with the latest updates. Let us count some of the important areas, tools, and features to observe, for example:
- Monitoring tools, log analysis, analytics (server, queries) — enterprises of all sizes and startups are frequently applying the monitoring and analytics tools as they offer a number of advantages, starting from full clarity of software performance to the possibility of tracking great-value pages. Such tools can help get steady releases in the future, providing reliable user services. For example, JSLogger has great features that help to start user activity monitoring on a site while managing your logs in the cloud.
- Detecting problems — issues with the programming must be detected at an early stage. “Troubleshooting JavaScript” and “Function Scope and Conflicts” are tools to detect problems.
- Useful operators — if you’re thinking how to make your code super modern or abstract, you can use Chaining and Coalescing. They help to make a readable and concise expression, simplifying some general tasks and avoiding a mass in your code.
- JS combined with web components — instead of using some big fat framework, you can start using web components and no-framework JS. Web components are remarkably raised in demand as they are much smaller than standard user interface components and they do not need extra run-time (they operate solely in a browser). So you will probably see major organizations start using them in 2020, improving performance; e.g., Apple created its Music store with a complete host of web components.
Tip #5: GraphQL & Its Exciting Possibilities
As exciting as it sounds, it is also the most notably helpful and beneficial tool to understand the existing data among all the latest JavaScript technologies. You can ask the client for what they are looking for and the developer can provide the same exact thing using GraphQL. Let us have a look at its exciting possibilities:
- What you want — GraphQL lets you send a query to the API and get predictable results. Major apps founded by the Facebook team are running on GraphQL and are more stable than others. Also, you can highlight the issues before sending the query.
- Single request, multiple resources — unlike any other tools, GraphQL helps to find multiple references and collects all the data you need in a single request. This also helps the apps to run faster even when the network connection is slow.
Tip #6: Apply Deployment Techniques
The frontend development is running so fast. Sometimes, newbies and even experienced JavaScript devs start to feel confused. In this light, let’s demystify some selected practices and see where you need to focus to efficiently improve JS performance:
- Data optimization — apply optimizations and start using less complex algorithms to create fine data structures;
- Query processing and database — focus on improving queries processing and try to apply queries optimization methods/techniques; pay attention to big query optimization in a complex database. Here, you can use monitoring tools to implement better solutions. You should also understand and get the basic idea of the database (a key element in-app performance) and types of databases;
- Write as you expect many users — you should expect that the developed service could potentially be used by hundreds of millions of people.
- Strategies and services for deployment — deployment is a crucial step. It’s possible to deploy the JS application on any server. Try to follow the latest tools, services, including CI/CD strategies for deployment.
Tip #7: ESLint Your Code
If you want a flawless coding system, ESLint is your answer. The smallest mistakes can lead to the collapse of the whole program. ESLint is a one-step solution to all coding related problems:
- Find Issues — although JavaScript has troubleshooting and error finding software, in-built ESLint is way simpler and faster. It is usually integrated into the whole system and is also a part of text editors. Additionally, TypeScript, TSLint, ESLint got together recently. Now, ESLint validates TypeScript by integrating TSLint’s features. It is great news, meaning these projects will be collaborating and providing an extremely powerful base for the team to leverage.
- Self-fixing — it is important for an app to be self-sufficient. ESLint is one of those apps that also fixes some insignificant issues as it is analyzing. ESLint is aware of syntax and semantics so after their correction, you won’t encounter any problems.
Tip #8: Test Your Code & Apply JavaScript Testing Tools
Once the code has been written, you would require to test it multiple times and correct it to have the desired result. To test the code, you would need state of the art JavaScript testing tools. We have prepared a shortlist of the most important testing tools:
These options are a time saving and efficient tools as they allow you to run multiple tests at the same time. You can check feedback and reviews to choose the best one for your needs.
Tip #9: Keep Up to Date with Important Developments in JS
For example, Svelte is a new tech that is loved by the JS community. It is always difficult to get what genuinely deserves your attention and should be explored.
However, Svelte offers access to new features that are worth paying attention to. It is one of the newest components-based JS user interface frameworks that produce code to manage DOM, improving runtime performance. Many teams have tried Svelte and gave positive feedback.
Tip #10: Serverless Approach for Certain Types of Operations
Serverless opens cloud development and it is going to be huge for front-end developers. Serverless is a new set of patterns to build, deploy, and operate solutions in the cloud epoch. It demands a new mindset to maximize benefits. A significant aspect of the architectures is the capability to provide continuous scaling, supporting large numbers of clients/users, events, and requests on the delivered app. It can help manage such challenges without worrying about infrastructure, focusing more on business needs.
If you want to build a high-quality app and offer a great experience, you can do this via a single JavaScript codebase on a serverless cloud platform. It is possible to use JavaScript to set up your cloud resources and start building and deploying serverless JS. In this light, you will modernize the environment with a reliable and safe serverless cloud platform. It is also a matter of operational costs of cloud computing, as you can save a load of money and maintenance debt in the long run when moving to systems like serverless. This is by far the best of all the latest JavaScript trends. If you follow the updates, you will see the serverless word does not look like an alien. You can actually start with it as it’s much easier than the traditional backend approach.
