JavaScript is a scripting language which helps you create interactive web pages. It followed rules of client-side programming, so it runs in the user's web browser without the need of any resources forms the web server. You can also use Javascript with other technologies like REST APIs, XML, and more.
The idea behind developing this script is to make it a complementary scripting language like Visual Basic was to C++ in Microsoft's language families. However, JavaScript is not designed for large complex applications. It was developed for applications with a few hundred lines of code!
In this Typescript vs JavaScript differences tutorial, you will learn:
Typescript is a modern age Javascript development language. It is a statically compiled language to write clear and simple Javascript code. It can be run on Node js or any browser which supports ECMAScript 3 or newer versions.
Typescript provides optional static typing, classes, and interface. For a large JavaScript project adopting Typescript can bring you more robust software and easily deployable with a regular JavaScript application.
Next, we will learn about the key difference between TypeScript and JavaScript.
Following is the main TypeScript and JavaScript difference:
Typescript Vs JavaScript
Parameter | Typescript | JavaScript |
---|---|---|
What is | Powerful type system, including generics & JS features | Lightweight, interpreted, object-oriented language with first-class functions |
Data Binding | TypeScript uses concepts like types and interfaces to describe data being used. | No such concept is available with JavaScript. |
Ecosystem | The Ecosystem is quite powerful and intuitive. Thus, it allows you to statically type various type of idiomatic JavaScript features like union types, intersection, discriminated union. | Javascript offers the option to explore and create code without a build step. |
Npm package | With Typescript, many npm packages either come with static type definitions or have an external one that is easy to install. | Javascript offers the option to explore and create code without a build step. |
Learning curve | Stiff learning curve. Requires prior scripting knowledge. | Flexible and easy to learn, scripting language. |
Prototyping | Typescript has a feature of prototyping. | JavaScript doesn't have this feature. |
Community | Typescript does not have a large community of developers. | The JavaScript has a huge community of developers |
Compilation | TypeScript code needs to be compiled | No need to compile JavaScript. |
Annotation | To get the most out of TypeScript features, developers should constantly annotate their code. | No Annotations Required is need for Javascript. |
Famous Company using the Technology | Asana, Clever, Screen award | Airbnb, Codecademy, Instagram |
Salary | The average salary for "Typescript developer" ranges from approximately $148,027 per year in United States | The average salary for a Javascript Developer is $110,777 per year in the United States. |
Netscape Communications Corporation programmer Brendan Eich created Javascript. It was meant to working Netscape navigator. However, after becoming a popular scripting tool, it is had become LiveScript. Later on, it was renamed as JavaScript to reflect Netscape's support of Java within its browser.

In the end of this JavaScript and TypeScript difference tutorial, we can say that if an experienced developer is working on relatively small coding projects, then JavaScript is ideal. However, if you have knowledge and expertise development team, then Typescript is a most preferred option.
