TypeScript vs JavaScript: Which is Better?
Since the post-pandemic, we are officially in the digital world where every organization wants to have an online presence. When it comes to launching an online solution, web solutions are the best and most cost-effective option, and even start-ups can launch their online web solution without spending a fortune. Although there are several options available to build a web app in a world where innovation and efficiency are paramount, choosing a reliable programming language is a must.
JavaScript has long been the foundation of web development, but with the rise of TypeScript, developers now have a powerful alternative. Now, several users are confused between JavaScript and TypeScript. What to choose?
If you’re also one of those users who wants to build a web solution but don’t know what language to use then you’re at the right place. In this blog, we’ll dive into TypeScript vs JavaScript, discussing the differences, pros, and cons, and which might be better suited for your next project. So, let’s not waste your time and dive straight into our topic.
What is JavaScript?
Whenever it comes to web development, JavaScript is the first name that hits the developer’s mind. It is one of the oldest as well as most advanced languages available nowadays. JavaScript is a dynamic programming language first introduced back in 1995, and in the last 29 years, it has gone through a lot of improvement and advancements. JavaScript powers most of the interactive elements you experience on websites today, and from front-end development with libraries like React to back-end frameworks like Node.js, JavaScript is everywhere.
Key Features of JavaScript:
- Dynamic Typing: JavaScript is one of the flexible languages as the variables in JavaScript do not require explicit type declarations.
- Interpreted Language: JavaScript code is executed directly by the browser, and developers don’t need to compile it.
- Event-Driven: JavaScript excels in handling user events, such as clicks, keystrokes, and more.
- Massive Ecosystem: JavaScript boasts a wide range of libraries and frameworks that effectively enhance productivity during development.
What is TypeScript?
TypeScript is a superset of JavaScript and was first released back in 2012 by Microsoft. The best thing about TypeScript is that it adds optional static typing and can catch errors at compile time rather than runtime. Optional static typing helps developers to write more predictable and error-free code.
Key Features of TypeScript:
- Static Typing: TypeScript introduces a type system that allows you to declare types for variables. These variables reduce the errors caused by unexpected data types.
- Transpiled Language: TypeScript must be transpiled to JavaScript before it can be executed by the browser.
- Enhanced Tooling: The static type system of TypeScript improves editor support and gives developers real-time feedback on code errors and auto-completions.
- Interoperable with JavaScript: Developers can gradually adopt TypeScript into existing JavaScript projects, as any JavaScript code is valid for TypeScript.
TypeScript vs JavaScript: A Detailed Comparison
1. Ease of Learning
– JavaScript: It is a simple, flexible, and dynamic language. JavaScript is quite easy to pick up, and beginners can get started with JavaScript in a quick manner. Its minimal setup and quick feedback loop also make it a favorite for rapid prototyping.
– TypeScript: On the other hand, TypeScript is more difficult for beginners, especially if the developer is unfamiliar with concepts like interfaces, types and generics.
Verdict: If you’re just starting out with web development, JavaScript is the easiest language to learn.
2. Development Speed and Error Handling
– JavaScript: It has a dynamic nature, which makes it easy to write for developers. However, its dynamic nature also comes with a loophole that is you’ll only catch the runtime error once you execute the error. This slows down debugging and error fixing.
– TypeScript: As stated earlier, Typescript is static typing, and developers can catch many errors during development, reducing the number of runtime issues. This saves time and effort in the long run.
Verdict: Typescript’s ability to catch errors early saves significant time during maintenance and debugging, so Typescript is the clear winner here.
3. Scalability
– JavaScript: JavaScript works great for small-to-medium-sized applications. But as your codebase grows, the lack of type safety makes JavaScript difficult to maintain.
– TypeScript: TypeScript has been the first preference for large-scale applications since its release. Its static-type system makes refactoring easier and safer.
Verdict: TypeScript is a clear winner.
4. Tooling and Editor Support
- Small Projects: If you’re working on a small project or a quick prototype, JavaScript is ideal. Its flexibility and ease of use allow for rapid development.
- Learning: If you’re just learning programming or web development, start with JavaScript. It will help you to grasp fundamental concepts quickly.
- Simplicity: If you need to write simple scripts or work on non-critical features, JavaScript’s dynamic nature is what you need.
5. Community and Ecosystem
– JavaScript: JavaScript has been in the market for over two decades and has an enormous ecosystem. Also, JavaScript has a vast array of libraries, frameworks, and resources. Hence, developers can easily find support, tutorials, and plugins for almost any project.
– TypeScript: Although TypeScript is new in the market, it is a superset of JavaScript, and typescript developers can tap into the entire JavaScript ecosystem.
Verdict: It’s a draw as the Typescript can also use JavaScript’s libraries.
We personally think Typescript is a clear winner in the comparison. Although it is newer in the market, it still offers advanced features. However, there are different use cases for both languages, and it completely depends on your need which language you prefer. So below is an overview of when to use both languages.
When to Use JavaScript
- Small Projects: If you’re working on a small project or a quick prototype, JavaScript is ideal. Its flexibility and ease of use allow for rapid development.
- Learning: If you’re just learning programming or web development, start with JavaScript. It will help you to grasp fundamental concepts quickly.
- Simplicity: If you need to write simple scripts or work on non-critical features, JavaScript’s dynamic nature is what you need.
When to Use TypeScript
- Large Applications: For large and complex applications, TypeScript is your go-to option. Its static typing helps with maintainability and prevents errors.
- Team Collaboration: If you’re working in a team, TypeScript’s type system ensures that everyone adheres to the same data types and structures, which reduces confusion and potential bugs.
- Long-term Projects: TypeScript’s error-catching capabilities will save time and effort during future development, which makes it a perfect option for long-term projects.
Conclusion: TypeScript vs JavaScript — Which is Better?
In the TypeScript vs JavaScript debate, neither language is definitively “better.” The choice of languages depends on the project requirement you’re working on. We’ve tried our best to give you an overview of both languages and their use cases. When it comes to building a small application or working with a tight deadline for prototyping, then JavaScript is your go-to place. However, if you’re working on a large-scale, complex application, then TypeScript should be your go-to option. If you still have any queries or want to build an application from scratch, we’ll help you with all your queries and suggest the best.
