Key Distinctions Between Typescript and JavaScript

Typescript is widely recognised as a superior alternative to Javascript due to its enhanced performance, and because it is compatible with both the front-end and back-end technologies.

Typescript provides a sophisticated yet scalable approach that outperforms Javascript in executing both server-side and client-side operations.

This triggered a debate on which one is more effective in web development – Typescript or Javascript.

For numerous years, Javascript has been a highly regarded client-side programming language in the IT industry. It has gained widespread popularity among IT professionals and developers who use it as a primary solution for developing web applications that can easily scale.

Roughly 95% of websites worldwide use JavaScript, however, this popular client-side programming language has some limitations when compared to other programming languages, which led to the creation of Typescript as a potential solution.

What are the characteristics of Typescript that make it more flexible than Javascript? What makes it a preferable alternative, and how do the two compare?

If you have queries about the disparities between Typescript and Javascript,typescript and javascript difference, this article has got you covered regardless of your level of expertise as a developer.

What is Typescript in contrast to Javascript?

With emphasis on syntax and typing, Typescript is an object-oriented programming language created by Microsoft. As a superset of Javascript, Typescript enables the development of large-scale applications. Typescript was initially launched in 2023, and it is open-source and free of cost.

Typescript is compatible with NodeJS and can run on all browsers that support ECMAScript3 and above. It has a user-friendly design that makes it easier to learn and use, which is why it is a favourite of both web and mobile application developers.

Introduced in 1995 by Benard Eich for Netscape, JavaScript is a free and open-source, multi-paradigm, object-oriented scripting language that has gained global popularity for its capacity to develop efficient and user-friendly online applications. It remains the world’s most widely used programming language.

As a client-side programming language, JavaScript harmonizes well with REST APIs and XML tools. A web browser is all that users require to execute JavaScript, without installing any additional software.

Why Typescript was Created

One may ask, with nimble programming languages like JavaScript already in existence, why the need for another alternative?

While JavaScript is ideal for client-side operations, it can become complex and inefficient when used on the server-side. Developers frequently identify these deficiencies, resulting in the creation of a separate language, TypeScript.

The Emergence of TypeScript and Deprecation of JavaScript

As illustrated in the chart above, Typescript and Javascript have distinct usage patterns. Although Javascript is still the most dominant scripting language, Typescript’s usage exceeds that of Javascript.

Contrary to popular belief, JavaScript remains the most favourable option for developing user-friendly websites. Developers and IT firms alike extensively employ it, with the support of an active community. Despite being utilised mainly for developing simple applications with minimal code, its potential should not be underestimated.

Typescript is a possible option for developing enterprise-scale software applications, as it offers the required flexibility and additional functionality for such projects. However, these large-scale applications could involve utilising thousands of lines of code. Unless there is a demand for extremely large applications, developers may prefer to employ JavaScript.

For the most part, projects have moderate sizes, rendering JavaScript a worthwhile selection. Additionally, firms may conserve time and energy by utilising the popular programming language, JavaScript, instead of teaching developers Typescript from scratch before creating the product. The choice between TypeScript and JavaScript will vary depending on the project’s size and scope.

Comparing TypeScript and JavaScript

1. Learning Curve Difficulty

  • Having a clear comprehension of JavaScript is pertinent to learning TypeScript, as it constructs projects on top of the former. Understanding diverse classes and interfaces and having a firm grasp of Object-Oriented Programming principles holds significance.
  • Acquiring proficiency in JavaScript can be accomplished within a brief duration, as it is a simple programming language. However, understanding Object-Oriented Programming (OOP) and related concepts is paramount to promoting the development of efficient software systems.

2. Community Support

  • Typescript’s swift adoption is apparent, attributable to its proficiency in constructing intricate applications. Apart from that, the online community provides exceptional assistance, enabling users to access adequate solutions to their inquiries easily. However, compared to JavaScript, the usage base of this language is still relatively small.
  • Since its inception, JavaScript has undergone substantial development, and now boasts an active community that provides prompt solutions to inquiries.

3. Execution

  • As a superset of JavaScript, TypeScript can expedite development by presenting developers with a diverse set of features in application construction. Nonetheless, the Javascript compilation onboarding process can be protracted.
  • JavaScript programmes hold a minor edge over TypeScript programmes as they can be executed without the need for compilation. Thus, while TypeScript may offer some benefits in terms of flexibility, JavaScript has the advantage of being faster in performance.

4. Support for Frameworks and Tools

  • Over the last decade, TypeScript has soared in popularity because of its ability to offer distinctive features unavailable in JavaScript. Consequently, various TypeScript frameworks have emerged, enabling developers to leverage its capabilities extensively.

Compilation Requires compilation It doesn’t require compilation
Prototyping Available Unavailable
Data Binding It uses types and interfaces to describe data being used. No such functionality is available.
Error handling Errors are found and fixed during compile time. Errors are found during runtime only.
Functions Optional parameter support No optional parameter

Comparison and differentiation of TypeScript and JavaScript capabilities.


  • TypeScript codes necessitate compilation before execution, which identifies errors promptly through the compilation window. TypeScript has a leading edge over JavaScript, mainly because of its superior functionality.
  • Typescript exhibits backward compatibility, making it compatible with previous versions of JavaScript, including but not limited to ES7 and ES12. Besides, it is proficient in running and executing programmes from both contemporary and archaic versions, rendering it as a highly versatile programming language. This stands as one of its best features.
  • JavaScript libraries can use TypeScript code for a broad range of web development projects. Moreover, TypeScript code is compatible with other JavaScript-based frameworks and applications.
  • Without a specific type being specified for a variable declared in TypeScript, TypeScript Language Service (TLS) has the ability to infer its type based on its value, similar to the JavaScript dynamic typing and type interface (JavaScript Type Interface).
  • As TypeScript is written in JavaScript, it is incredibly portable and does not mandate a virtual machine (VM) or runtime environment for executing it in browsers, mobile devices, and other platforms.

2. JavaScript

  • JavaScript provides an extensive set of tools that enable the detection and response to events. An event is essentially an action signal that necessitates a response from the software to complete a task. For instance, when a user clicks a button to gain access to a specific area of the system, the software has to reciprocate accordingly. JavaScript empowers developers to personalize these events to fit their requirements.
  • Most up-to-date web browsers are equipped with scripting engines that can interpret and execute JavaScript commands, enabling JavaScript to run on any platform that supports the associated web browser.
  • Just like Java, JavaScript incorporates control statements, such as if-else, do-while, and switch cases, allowing the creation of sophisticated and dependable online solutions. Additionally, it is renowned as a robust programming language for building a broad spectrum of applications, courtesy of its control statements and functions.
  • Both data and time hold immense significance, and fortunately, JavaScript consists of an in-built technique for calculating both variables.
