If you’re a developer or an aspiring developer who wants to build his/her career in the same field – JavaScript is one such language that can help you in becoming one and can also earn well. It is the most popular and in-demand programming language in the IT world. JavaScript was on its verge when the developer who created it, created another scripting language – TypeScript. TypeScript vs JavaScript has been a hot topic in the IT industry.
Since the time TypeScript came into existence, there has been a battle of typescript vs javascript – which is best? In this blog, we’ll discuss some of the major differences you should know before starting to work on a project.
Both JavaScript and TypeScript is the hot topic in the IT industry. Let’s see who is better than the other.
What is TypeScript?
TypeScript, developed by Microsoft in 2012, was developed so as to handle large-scale applications. It is a superset of typed JavaScript, you can also say it is JavaScript with more features. It means if you compile a program in JavaScript and save it as a .ts extension instead of .js (for JavaScript), it’ll work well. It is an object-oriented programming language and is strongly typed which makes it suitable for large projects since it debugs better. Some of the top companies which use TypeScript are Microsoft, Accenture, and Slack.
JavaScript + Extra Features = TypeScript
Features of TypeScript –
- Static typing and annotations
- Easy to debug
- Supports ES6 (ECMAScript)
- full-fledged IDE support
- TS code can be converted into plain JavaScript code
- Allows better development time tool support
- Compatible with any browser
- Enhances productivity
What is JavaScript?
JavaScript, developed by Netscape in collaboration with Sun Microsystems, is one of the most popular and in-demand programming languages. JavaScript plays a very important role in building interactive and dynamic web applications. It is used to build small-scale projects and the syntax is similar to Java. Also, JavaScript can be used to work on both front-end and back-end development. Some big companies that use JavaScript are Microsoft, Netflix, Google, PayPal, and Uber.
Features of JavaScript –
- Cross-platform, flexible, and dynamic.
- Used for both client-side and server-side implementation.
- Supported by all browsers
- Adds support for classes, interface, and module
- Extendable and versatile (builds mobile, desktop, and web apps)
- Lightweight and interpreted, helps to create fast and responsive web apps
- Large community of developers

| Has a feature of prototyping | doesn’t have the feature of prototyping |
| Errors are detected at run time | Errors are detected at the early stage of development |
| Supports data binding | Does not support data binding |
| Used to build large-scale applications | Used to build small-scale applications |
| Does not have a huge community of developers | Has a huge community of developers |
| Annotate codes constantly | Annotation is not required |
