Top 10 Javascript Alternatives For Front-End Developers

Everything over the web is in Javascript. Javascript is the most used programming language with approximately 97% of websites using Javascript as a client-side programming language. Everything around us is Javascript ranging from iPhones, Macs, Androids, OS, Linux, etc. Learning and understanding the language helps create the most complex applications with utmost ease.

This vast usage of Javascript goes to its compatibility with both front-end and back-end and its ability to run on all devices. This programming language does not require an initial setup and can be integrated with various third-party libraries for better performance and efficiency. In this article, we’ll be going through Javascript first followed by its alternatives that can be used in its place for frontend development.

What is Javascript?

Javascript or JS is a programming language. It is the core technology of the World Wide Web (WWW) alongside HTML and CSS. It is a lightweight, single-threaded, cross-platform, and interpreted compiled programming language. This scripting language allows the developer to create dynamic content, and control multimedia on a website. It is a powerful language that can update and change HTML and CSS. It works seamlessly alongside HTML and CSS, making the webpage more interactive and easy to interact with. Javascript is a valuable application in web, mobile app, and game development that makes it important to learn and understand.

Why Javascript?

The following features of Javascript make it an excellent choice among a pool of various programming languages:

• Simplicity: JS is an easy-to-use programming language with a simple syntax and is beginner-friendly.
• Client-side execution: The code is executed on the client-side making it a more convenient language.
• Validation: Client-side validation helps save bandwidth from getting wasted and also saves time.
• On Browser Debugging Support: Developer Tools on every browser helps debug the code on the browser itself.

Need for Javascript alternatives

The following drawbacks of javascript make room for new alternatives to emerge:

• Security: The client-side code execution is less secure than the code executed on the server side.
• Stucked rendering: Code execution stops in between the loads in case of any bugs.
• Inheritance: JS only supports single inheritance and does not support multiple inheritance.

It provides certain advantages custom components, dependency injection, testing and browser compatibility along with proper structure to help developers write code efficiently.

Features

• Document Object Model (DOM): Angular uses DOM and is efficient when multiple updates are applied on an HTML page as it considers XML and HTML files as a tree data structure.
• Typescript: Angular uses Typescript which provides an easy way to code in Javascript by giving a higher syntactical structure to the code by defining kinds of Javascript.
• Data Binding: It helps manipulate the web page via interactions on a web browser. For example in applications like calculators, forums, games etc.
• Testing: Angular uses the Jasmine framework to write check cases for your code.

2. Dart

Dart is an open-source general-purpose programming language designed by Lars Bak and Kasper Lund and developed by Google. It is a language used for server-side as well as client-side. It can be used to create web applications, mobile apps or desktop applications. It is an object-oriented, garbage-collected language with syntax very similar to C.

Features

• Object-Oriented Nature: Dart is an object-oriented language supporting abstraction, inheritance and various object-oriented concepts.
• Cross-Compatibility: Dart is supported by all operating systems. This cross-platform functionality of Dart is achieved as Dart compile runs on its virtual machine.
• Asynchronous Programming: You can run your program without getting blocked. The single-threaded programming nature of Dart makes sure that important functions are executed till execution.
• Ahead-of-time: The Ahead-of-time compilation of Dart helps convert Dart code into native machine code.

3. React

React is an open-source front-end Javascript library maintained by Meta. It is used to build user interfaces, single-page applications and reusable UI components. It can be used to create web, mobile and desktop applications making it a cross-platform compatible library. Apart from UI, it provides extensions for various architectural support to the application.

Features

• Javascript Syntax Extension (JSX): JSX is a combination of HTML and Javascript and can be used to embed Javascript objects into HTML tags making code easy and more understandable.
• Virtual DOM: Using Virtual DOM, React creates a copy of the original DOM and makes the changes in that DOM first and then compares the updated DOM with the original DOM and only changes the parts that need to be updated.
• One-way Data Binding: React follows one-way data binding i.e. data flows in one direction only. The data flows from the parent component(s) to the child component (s).
• Conditional Statements: Using JSX you can implement conditional statements to your web page and view the page according the the condition existing at that moment.

4. TypeScript

Typescript is a free and open-source programming language developed by Microsoft. It adds static typing with type annotations to Javascript. It is used for the development of large applications and transpiles to Javascript. Its object-oriented, highly scalable and cross-platform features have made it an active choice among developers.

Features

• Object-Oriented Nature: Typescript is an object-oriented language supporting abstraction, inheritance and various object-oriented concepts.
• DOM: Typescript uses DOM and is efficient when multiple updates are applied on an HTML page as it considers XML and HTML files as a tree data structure. It uses DOM features similar to Javascript.
• Portability: Typescript can be executed on any browser, device or operating system and does not require a virtual machine for execution.
• Javascript Support: You can use every Javascript element, framework and tool in Typescript.
