![Top 7 Frontend JS Frameworks & Libraries in 2023 [Updated]](https://bambooagile.eu/wp-content/uploads/2021/09/1-16.png "1 (16)")
What is JavaScript?
JavaScript is a cross-platform programming language that allows you to work with frontend, backend, and mobile app development. It is considered to be one of the most popular and demanded programming languages worldwide. Today, almost no web page is complete without JavaScript-based interactive features.
What is a JS Framework?
JS frameworks are tools for building dynamic web, mobile, and desktop applications in the JavaScript language. With their help, you can develop full-fledged sites and functional modules alike. Full-fledged frameworks are much better suited for the first task, while for the second, it is recommended to use lighter weight frameworks or libraries.
The State of JavaScript In 2023
The world of JavaScript is constantly transforming and evolving.
StackOverflow survey results showed that JavaScript is the most commonly used programming language across the web.
By the year 2023, 57.8% of developers agreed that JavaScript is progressing in the correct direction and nearly 19% of developers strongly confirm this statement.
In terms of how satisfied survey respondents are with the general state of web technologies, the findings are as follows:
More than half of survey respondents are happy with the state of web tech as a whole compared to less than 5% of unhappy ones.
Back to the StackOverflow results, React.js has the position of the most used frontend framework.
The advantages of using JS Frameworks
From a large number of advantages, we can distinguish several key ones:
-
- Easy implementation of SPAs (Single Page Applications) and PWAs (Progressive Web Applications);
- Organised application structure;
- Shorter and cleaner code, which positively affects the speed of development, as well as the support and elimination of errors;
- App modularity, which makes it easier for several developers to work on the application simultaneously;
- The ability to quickly create a mobile and/or desktop cross-platform application from its web version using systems such as PhoneGap or Apache Cordova.
Angular
Angular is a framework from Google for building client applications. First of all, it is aimed at developing SPA solutions. In this regard, Angular came from Angular JS. At the same time, it’s not an update to its predecessor, but a fundamentally new framework.
Advantages:
- Thanks to the size of its community, there is a huge number of books, online resources, and conferences dedicated to Angular. This allows developers to stay relevant, and lets clients easily find companies to support their project.
- When creating templates in Angular, the declarative programming paradigm is applied, which makes the script more lightweight and easier to read and maintain. It happens due to the fact that the code describes the needed result instead of the steps required to accomplish it.
- A large number of useful features allows you to create the most user- and developer-friendly SPAs.
- Angular lets you organise applications from separate modules, which can be mutually dependant or autonomous.
- Angular modules are versatile and easy to manage. This modularization allows developers to load only the services they need at a given time, thus making automated testing more efficient. Plus, there is no need to remember the order of loading modules in case you adhere to the principle of “one file – one module”.
- Angular uses two-way binding: any changes in the user interface are immediately reflected in the application objects and vice versa. The framework itself monitors browser events, model changes, and user actions on the page to immediately update the necessary templates.
Angular Updates
Since the release of our article, there have been two large updates of Angular. Here is the list of the new features in a few words.
What was new in Angular 14:
- A new feature called Standalone Component enables you to build your own components and use them anywhere in your app. The biggest benefit of standalone components is that you don’t have to worry about whether they’ll function with all the other various features of your app because they’re simpler to customise than other types of components.
- A rigid form of types can now be imposed on your forms using TypeScript. This makes it simpler to ensure that your forms are valid because each entry will be checked against its type when it is submitted and validated.
- The new Angular CLI functionality known as Angular CLI Auto-Completion offers auto-completion for the Angular command line interface (CLI). The feature uses the IntelliJ IDEA Plugin, which is built on TypeScript definition files.
- A brand-new diagnosis technique known as ng-template-error is available. When your application throws an error during runtime, this diagnostic will display the offending code within the error message.
- You can immediately alter the title tag of your pages from the <head> of your stylesheet. Now that HTML has more capabilities, you can input more information in the title tag.
What is new in Angular 15:
- Single-file components. This function is very important. It implies that component layouts can now be created as separate files rather than components. Sharing common styling choices and other components between apps or files will be easier as a result.
- Module loaders. Another intriguing new tool for Angular developers is module loaders. They enable users to import the appropriate modules at runtime without relying on WebPack or a similar loader. Any build system you use, such as Babel, Webpack, or Gulp, can be hacked with a module loader. Additionally, they don’t require any additional expenses because they are so lightweight.
- New API system. A new API method is presented in Angular 15 to make it simpler for developers to use modules. They can now be used out of the box – a significant shift from the previous versions, which lacked built-in support for them. With the new API system in Angular 15, interacting with APIs is also made simpler, since you no longer need to create code for every endpoint. To build data models, gain access to authentication systems, and work with JSON data from an API endpoint, you can use already existing tools. And having less written code improves the performance of your program.
- Stability. The new Angular 15 is compatible with earlier iterations of the framework. This is a crucial feature because it allows you to continue using your current applications without having to think about them evolving over time. Access control for form inputs has been enhanced with the new forms in Angular 15. Now you can limit input values based on type or length, making your forms more secure and less error-prone, no matter the intricacy.
- Image directive. A new directive called the image directive can be used to add a picture to the DOM. You can also select its size and placement on the screen. A brand-new HTML markup rule is the Image rule. The input and the output are its two components. Anything from file paths to picture arrays can be used as input. You can define the CSS and JavaScript for your image as well as any other styles required for your app in the output.
- MDC Based Component. The MDC-based component is a brand-new type of component that enables you to use TypeScript to create your components in a much more declarative manner than before. It also makes it simpler to modularize your application by allowing you to use additional modules like NgModule and components. So rather than constantly inventing the wheel, you can reuse your components in various applications.
