As its name suggests, it allows for optional types that JS does not. It uses JS syntax and semantics plus additional features that help developers improve their productivity and efficiency. Below are some of the reasons why TS continues to be a powerful and popular trend in JS.
1. Compile-Time Bug Detection
Like JS, TS detects program errors by highlighting unexpected behaviors. This bug detection feature happens during compilation as opposed to execution. Through this, TS can generate more efficient code.
2. Static Typing
TS allows developers to create complex types by combining existing ones. TS can do this because it uses structural or duck typing. This is also the reason why TS can employ unions and generics. Plus, TypeScript supports different interfaces.
3. Offers Large-Scale Solution Support
4. Easy to Learn for JS Developers
TypeScript uses JS syntax and other features. For these reasons, it is easier to learn for JS developers. These features make TS a popular programming language. According to Stack Overflow’s 2021 Developer Survey, it is the third most loved language. And all developments indicate that TS will only continue to trend upwards as we enter the 2nd half of 2022.
Angular.js, on the other hand, is in an interesting position. Although almost half of the developers use the framework, the number of developers who want to learn it is low. This is because developers agree that Angular.js is harder to learn. Also, it is mostly used to develop large and complex projects.
That said, React.js maintains its hold at the top of JS frameworks. The framework’s constant improvement of its features ensures that both clients and developers still want to use React as their front-end framework. Its features make it more convenient and optimized for the 2022 web development landscape. This includes hooks, component-based servers, and concurrent mode.
Another interesting trend in regards to the JS back-end side is the continued rise in popularity of Fastify. This tool provides developers with a faster alternative for Express.js.
The rise of Fastify and other backend frameworks should encourage the development of more efficient systems. These systems should be able to handle more queries at a lower cost.
All the Jest at the Testing End
Jest still reigns as the top testing library in 2022. This should come as no surprise due to the wide use of React. Additionally, Jest is a bootstrapping tool that every React users use.
On the other hand, Jasmine, which is Angular’s default testing tool, is experiencing a decline in its usage and popularity. Another alternative is Mocha. However, most developers are not a fan of the process of setting up the tool before they can start testing.
Web Components as Building Blocks
- Custom Elements – creates new autonomous HTML tags. These tags have fully-customizable behaviors.
- Shadow DOM – allows for encapsulating of DOM subtrees to web elements.
- ES Module – helps determine JS modules and reuse them in other JS documents.
- HTML Template – helps developers create markup fragments. These fragments are instantiated during runtime to avoid slowing down the load time.
Web components are very flexible and have good support from popular frameworks and libraries with these features. In addition, because web components are small in size and have quick runtime, they are a great help for progressive web apps.
