While both of these programming languages are mostly used for web application development, but lately the TypeScript has gained rapid traction ever since RxJS and Angular started adopting it.
Reading this blog will definitely answer that question.
It is a client-side programming language which doesn’t need any resources from the web server.
The main idea behind developing this language was to make a complementary scripting language, just like Microsoft has Visual Basic to C++.
- In 1998 & 1999, ECMAScript 2 and ECMAScript 3 was released respectively.
- In 2009, the CommonJS project was created for driving the language towards ECMAScript 6.
What is TypeScript?
TypeScript can run on any browser that supports ECMAScript 3 or new versions, including Node JS.
History of TypeScript
TypeScript was created by Microsoft as an open-source programming language with optional static typing.
- TypeScript was released for public in October 2012 as version 0.8.
Version 0.9 was released in 2013.
- Microsoft then added support for generics and released TypeScript 1.0 at Microsoft’s build developer conference 2014.
- In July 2014, TypeScript development team at Microsoft released a new TypeScript compiler, claiming 5 times more performance.
- In September 2016, Microsoft released TypeScript 2.0 that comprised several new features, including the feature of optionally preventing variables from being assigned null values.
- In March 2018, conditional types were added in the TypeScript.

Benefits of TypeScript
Like mentioned in the beginning, TypeScript is gaining traction rapidly. And the main reason behind that is its benefits from additional features. Following are the best benefits of TypeScript.
In TypeScript, the static typing feature helps to detect bugs while writing the scripts.
One of the main objective of TypeScript is to statically identify constructs which are possibly errors.
This basically allows developers to make safe assumptions about state while in execution.
To understand better, take a look at below example.
But, this can be easily avoided in compile time if you use TypeScript Annotations shown in below example.
As you can see, the above code will prevent operations from executing if the object type is unexpected.
Better for collaboration
Large-scale applications usually have more developers working on its development. This creates an opportunity to create mess and increase coding errors.
However, the type safety feature in TypeScript helps to find code errors and bugs while writing the code and not during compilation, which results into more efficient debugging process and better collaboration opportunity.
Take Fetch API for example. The below given image shows how developers can explore the API using the VSCode Peek feature.
Perfect for large-scale application development
Most large-scale projects require small and incremental changes to its code base.
And these changes must be done carefully otherwise it creates significant & unintended consequences.
TypeScript refactoring tools helps in avoiding such situations by providing an option to undo the changes, making the development process a lot easier and faster.
TypeScript has in-built features like auto-compilation, ECMAScript 6 code support, and dynamic typing that helps compiler in creating highly-optimized code and boosting developers’ productivity.
Build tools required
Strong test workflow
If your project involves using libraries, then TypeScript will need their type definitions. And every type definition will add an extra npm package.
The point is, depending on these dependencies will just add the risk of these packages going un-maintained or become incorrect in future.
Simply put, if you need to import type dependencies in your application development, then you would lose the TypeScript advantage.
This is where TypeScript can come to rescue. TypeScript allows dynamic approach and also provide proper structure through its type checking feature.
Create big applications
If you’re creating an enterprise-level application or product in which structure to the system is required, then TypeScript is recommended.
The Reason is, TypeScript makes it easy to develop and maintain the project with fewer bugs.
- There will be a lack of Object Oriented Programming
- No base structure of the project
- Lastly, no inherent type hinting/type casting.
Type hinting/type casting
Once a number is assigned, TypeScript then shows the error while writing the coding so that developers can resolve it before deploying the final code.
Targets multiple browsers
TypeScript allows you to write the code once and specify right then and then which browser to target. In short, TypeScript takes care of the behind the scenes.
Tech giants are already using TypeScript…are you?!
Google’s Angular, for example, the one that changed the modern front-end development forever with its two-way data binding, now uses TypeScript as a primary build block.
The point is, there are many other frameworks, other than Angular and Ionic, which provide TypeScript as an language option.
