Do you need help deciding whether to use TypeScript or JavaScript for your coding needs? Well, you’re at the right place because we are here to lend a hand and provide some guidance on this topic.

These two programming languages can have some similarities. But have you ever wondered how they’re different? Like, is TypeScript a smaller version of JavaScript, or which one is better? Let’s dig into this blog post together to find answers to Typescript vs. Javascript.

What is JavaScript?

JavaScript is an incredible programming language that makes web pages interactive. It works on the user’s browser so it’s super smooth. And get this; it can even work with other cool technologies like XML and REST APIs. 

History of JavaScript

Brendan Eich created JavaScript at Netscape Communications in 1995. It was designed for the company’s flagship browser as a scripting language, which is called Netscape Navigator. Earlier, JavaScript was known as LiveScript; Netscape changed its name to JavaScript to reserve a spot as a companion for the Java language. 

In 2008, Google’s open-source Chrome V8, a high-performance JavaScript engine, gave a critical point for JavaScript.

Features Of JavaScript: 

  • Fewer error messages
  • Easy-to-use interface with less confusing advanced features
  • Ability to write less code 
  • Unexpected results
  • Easier learning curve

What is TypeScript?

As JavaScript grew in popularity, its code became complex and cumbersome. This made it difficult for JavaScript to meet the standards of an Object-Oriented Programming language. This affected its success as a server-side technology in big business environment. To solve this, the JavaScript development team created TypeScript to bridge this gap.  

History of TypeScript

TypeScript is a relatively modern programming language. It was launched as version 0.8 for public use in 2012. It resulted from two years of development at Microsoft, with Anders Hejlsberg, the lead architect of c# and the creator of Delphi and Turbo Pascal, working on the project too.

TypeScript is an open-source programming language used to create high-level applications. In 2012, one of the technology behemoths, Microsoft, made TypeScript. The primary motivation for TypeScript creation was to manage large-scale applications.

Features of TypeScript: 

  • Minor problems and bugs
  • Type definitions to improve the autocomplete feature
  • Writing more code
  • Predict how your code will run
  • The learning curve is a bit higher

Pros and Cons of JavaScript

Pros 

  • JavaScript is an interpreted language, so it reduces the time of compilation.
  • It is easy to understand and learn.
  • JavaScript is 100% interoperable with Java, so many developers prefer using it for developing applications. 
  • It has several varieties of interfaces for creating catchy web pages.

Cons 

  • It is only used for small projects, not for complex projects.
  • Tools for construction are necessary.
  • The test workflow is robust.
  • Dependencies on type are essential.

Pros and Cons of TypeScript

Pros 

  • Typing allows for precise definitions.
  • Its Code management is simplified.
  • Team performance has improved.
  • TypeScript detects compilation bugs throughout development. As a result, the scope of analyzing errors at runtime is significantly reduced.
  • Static typing is supported by TypeScript. 

Cons

  • It is too difficult to learn if just considered a static type checker. 
  • It is necessary to learn JavaScript before learning TypeScript.
  • TypeScript takes more time to compile the code.
  • TypeScript developers are hard to find because a limited number of TypeScript developers are available out there.

TypeScript vs. JavaScript: Key Differences

typescript vs javascript differences

Let us now discuss the head-to-head comparison between TypeScript vs JavaScript. While comparing both of them, we have to consider the following factors

Static Typing vs. Dynamic Freedom

TypeScript brings the structure of a well-planned itinerary with its static typing, while JavaScript offers the thrill of spontaneous exploration with its dynamic typing.

Compilation vs. Direct Interpretation

TypeScript’s need for compilation is akin to preparing a fine dish, requiring careful steps, while JavaScript’s direct interpretation is like enjoying street food – quick, immediate, and satisfying.

Detective Work in Development

TypeScript acts as a vigilant sleuth, catching errors in the early stages of development, whereas JavaScript plays the surprise storyteller, keeping potential errors hidden until runtime.

Legibility and Storytelling

TypeScript’s type annotations weave a clear narrative in the code, much like a well-written book, while JavaScript, with its flexibility, allows for imaginative interpretations like an open-ended tale.

Vast Landscapes of the Development World

JavaScript boasts an expansive and bustling city of libraries and frameworks, while TypeScript, though growing, might resemble a charming village with a more intimate community.

Learning Curves

JavaScript’s ease of learning is akin to riding a bicycle on a familiar path, whereas TypeScript, with its added intricacies, might feel more like mastering a thrilling new sport.

Compatibility and Evolution

TypeScript’s embrace of all JavaScript code is akin to a welcoming host, inviting existing projects to gradually join its refined gathering without excluding anyone.

TypeScript vs JavaScript: The Differences

Why You Should Pick Typescript Over JavaScript

TypeScript is a fantastic tool for web development. It helps to keep your code arranged and easy to maintain. With TypeScript, you get a static typing system that catches errors before they even happen. This makes it way easier for you to debug your code. Plus, it’s object-oriented, with features like classes and interfaces to scale up your projects. And the best part? TypeScript is compatible with JavaScript. This allows you to use it with your existing projects without starting from scratch. There might be a learning curve initially, but the benefits are worth it. You can achieve better performance, better tools, and better code quality. 

If you’re serious about web development, try TypeScript for your next project. Let’s understand how TypeScript can change your development game through some reasons:

  • You can easily create big or complex applications. 
  • You will have a more reliable source than JavaScript. 
  • You have the ability to utilize all JavaScript code and libraries.
  • You can easily convert a variable from one type to another.
  • You can target multiple web browsers. 
  • You can leave comments while typing code for future reference.

Is TypeScript the future of JavaScript?

TypeScript is a distinct language from JavaScript, though it shares some basic characteristics. JavaScript remains a popular and essential technology in software development, used by countless developers for server- and client-side applications.

TypeScript, on the other hand, must be trans-compiled to JavaScript to execute in web browsers. Therefore, each programming language has advantages and disadvantages and a unique set of characteristics. 

To keep up with the latest trends in enterprise web development, businesses must adopt new technologies or frameworks to improve business processes and enhance customer experience.

Conclusion

As a user, you can decide which language is more suitable for your project. While JavaScript remains a popular choice among developers due to its versatility and large community, TypeScript offers additional features such as OOP concepts and generic features, making it a great option for complex projects with a large codebase. Both languages have their strengths and weaknesses, so choosing the one that best fits your needs is up to you. Ultimately, the decision should be based on the specific requirements of your project.
