Differences between TypeScript and CoffeeScript


CoffeeScript is a dynamic, imperative, scripting, multi-paradigm, prototype-based, imperative, and functional programming language, which is used to transpile the code into JavaScript. Its syntax is close to Python, and Ruby programming languages. CoffeeScript provides clear visibility for complex and large-scale applications development.

Jeremy Ashkenas designed and developed CoffeeScript in the year 2009. CoffeeScript is licensed under the MIT License. The filename extensions for the CoffeeScript files are .coffee or .lit coffee. Its syntax is similar to JavaScript and has a lot of features, which provides greater flexibility for the code readability. It also provides tools which are similar to the Ruby and Python languages.

CoffeeScript compiles the code one by one into the equivalent JavaScript code, and there is no interpretation at the runtime. The compiled output is readable and will work in every other JavaScript application or usage, and aims to run much faster than the plain equivalent handwritten JavaScript.

Advantages of CoffeeScript

  • It is a reliable programming language, which supports for writing dynamic programs.
  • It provides aliases for most of the operators, which makes the code readable.
  • The programs written in CoffeeScript is also easy to maintain.
  • It provides chained comparisons, object iteration, parallel assignments, etc.
  • It is easy to understand.
  • It is easy to read & maintain the code.


TypeScript is an open-source pure object-oriented programing language. It is a strongly typed superset of JavaScript which compiles to plain JavaScript. TypeScript is developed and maintained by Microsoft under the Apache 2 license. It is not directly run on the browser. It needs a compiler to compile and generate in JavaScript file. TypeScript source file is in ".ts" extension.

We can use Typescript for both server-side and client-side web applications. It is also used in the development of large-scale web applications. It adds support to the different features present in ECMAScript which is maintained by a TC39 committee of the ECMA group.

Anders Hejlsberg developed TypeScript. Its first version introduces to the public in the month of 1 October 2012. After two years of internal development at Microsoft, the new version of TypeScript 0.9 was released in 2013. The current version of TypeScript is TypeScript 3.4.5 which was released on 24 April 2019.

Advantages of TypeScript

  • It is used for both server-side and client-side language.
  • It is an open-source and object-oriented programming language.
  • It is best for large scale projects.
  • It provides support for ECMA Script 6 feature.
  • It is a superset of JavaScript.

TypeScript vs. CoffeeScript

We can understand the main differences between TypeScript and CoffeeScript from the below table.

TypeScript vs. CoffeeScript
TypeScript CoffeeScript
Introduction It is an open-source, dynamic, and high-level programming language. It is a lightweight programming language which provides support for JavaScript language.
Maintenance It is developed and maintained by Microsoft under the Apache2 License. It is developed and maintained by the developer community itself under the MIT License.
Relation It is a superset of JavaScript. It supports most of the JavaScript features. It is the enhanced version of JavaScript.
Platform It can run on any browser to display the dynamic content. It requires any JavaScript engine to run the code.
Web application TypeScript is used for both server-side and client-side web application. CoffeeScript is used for server-side web application only.
Use of Interfaces TypeScript has high support for the use of interfaces. CoffeeScript has low support for the use of interfaces.
Compatibility TypeScript supports almost all browsers. CoffeeScript supports contents in the browsers which depends upon specific functionalities.
Capabilities TypeScript has high object-oriented capabilities. But it is a strictly typed programming language. CoffeeScript has high object-oriented capabilities. But it is a dynamic type of programming language.
When choose TypeScript/CoffeeScript TypeScript is best when we want static type checking and better tool support. CoffeeScript is best when we want more concise code and lots of syntactic sugar.
Latest version The 3.5.3 is the current stable version of TypeScript. The 2.4.1 is the current stable version of CoffeeScript.
