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.
