CoffeeScript的是一个动态的,必要的,脚本,多范式的,基于原型,势在必行,和功能性编程语言,其被用于将代码transpile成JavaScript。它的语法接近Python和Ruby编程语言。 CoffeeScript为复杂的大规模应用程序开发提供了清晰的可见性。
Jeremy Ashkenas在2009年设计和开发了CoffeeScript。 CoffeeScript是根据MIT许可授权的。 CoffeeScript文件的文件扩展名是.coffee或.lit coffee 。它的语法类似于JavaScript,并且具有很多功能,从而为代码的可读性提供了更大的灵活性。它还提供了类似于Ruby和Python语言的工具。
CoffeeScript将代码一一编译为等效的JavaScript代码,并且在运行时没有解释。编译后的输出可读,可在其他所有JavaScript应用程序或用法中使用,并且其运行速度比普通的手写JavaScript快得多。
CoffeeScript的优点
TypeScript是一种开源的纯面向对象编程语言。它是JavaScript的强类型超集,可编译为纯JavaScript。 TypeScript由Microsoft根据Apache 2许可开发和维护。它不是直接在浏览器上运行。它需要编译器才能在JavaScript文件中进行编译和生成。 TypeScript源文件的扩展名为“ .ts”。
我们可以将Typescript用于服务器端和客户端Web应用程序。它也用于开发大型Web应用程序。它增加了对ECMAScript中存在的各种功能的支持,该功能由ECMA组的TC39委员会维护。
Anders Hejlsberg开发了TypeScript。它的第一个版本于2012年10月1日向公众发布。经过Microsoft两年的内部开发,TypeScript 0.9的新版本于2013年发布。 TypeScript的当前版本是TypeScript 3.4.5 ,该版本于2019年4月24日发布。
TypeScript的优点
从下表我们可以了解TypeScript和CoffeeScript之间的主要区别。
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. |
