Groovy 和 Scala 的区别

 常规：

Groovy 是一种面向对象的高级编程语言，与Java语法兼容。它被用作Java平台的编程语言和脚本语言。 2004 年，Bob McWhirter 和 James Strachan 开发了 Groovy 语言。 Groovy 的源代码被编译成字节码，因此它可以在任何安装了 JRE(Java运行时环境)的系统中运行。

使用 Groovy 语言的公司有 Craftbase、Starbucks、AgaroPulse、TransferWise、Trendyol Group 和 Rumble 等。

Groovy 的优点：

• 简单的文件操作
• 简单易学
• 静态和动态类型

Groovy 的缺点：

• 无基本代码格式
• 非懒惰评估
• 性能不是很好

 斯卡拉：

Scala 是一种通用的高级编程语言，支持面向对象编程和函数式编程的概念。它是一种可扩展的语言，用于为多个平台编写软件。 2003 年，Martin Odersky 先生和他的研究团队发明了 Scala 语言。 Scala 源代码首先通过 Scala 编译器生成字节码，然后将字节码传输到 JVM(Java虚拟机)以生成输出。

使用 Scala 语言的公司有 LinkedIn、Twitter、Coursera、Netflix、Sony、Foursquare 和 Asana 等。

Scala 的优点：

• 易于学习，代码简洁且无错误。
• 可扩展编程语言
• 很好的IDE支持

Scala 的缺点：

• 有限的开发者池
• 有点难以理解，因为它是面向对象和函数式编程的结合。

Groovy 和 Scala 的区别：

	GROOVY	SCALA
1	Groovy is an object-oriented high-level programming language that is Java syntax compatible. It is used as both a programming language and general-purpose scripting language for the Java Platform.	Scala is a general-purpose, a high-level programming language that supports the concepts of both object-oriented programming and functional programming which is used to write software for multiple platforms.
2	In the year 2004, the Groovy language was developed by Bob McWhirter and James Strachan.	In the year 2003, the Scala language was invented by Mr. Martin Odersky and his research team.
3	It is not a pure object-oriented language.	It is a pure object-oriented language.
4	It can be used as a scripting language like log configuration.	It can be used for building applications in the big data domain.
5	It supports multiple inheritances.	It supports multiple inheritances using traits.
6	It is a dynamically-typed language.	It is a statically typed language.
7	It is syntactically influenced by Java.	It is syntactically influenced by both Ruby and Java.
8	It uses the static concept.	It has no concept of “static” fields, inner classes, methods, etc.
9	Public is the by default access modifier.	Here also Public is the by default access modifier.
10	Native support is provided for Markup languages like XML & HTML.	Whereas in Scala generating HTML docs support is provided by using The top language.
11	It has integrated tools like Java and Grail.	It has integrated tools like Java, ScalaNLP, etc.
12	The top 5 IDEs and text editors for Groovy include Groovy/Grails Tool Suite, TextMate, UltraEdit, IntelliJ IDEA, GroovyEclipse.	The top 5 IDEs and text editors for Scala include a dispatches the  Scala IDE for Eclipse, ENSIME, IntelliJ IDEA, NetBeans, VIM.
13	Groovy is good for rapid prototyping development delivering higher performance as it has a faster compile cycle.	Scala seems slower in compilation but it has a faster execution cycle.
14	It has “accidental” multiple dispatches and the G Pars library offers concurrency and parallelism for the application.	It is single dispatch only and the use of JVM behaves well on single-threaded that performance,
15	Companies that use the Groovy language are Craftbase, Starbucks, AgaroPulse, TransferWise, Trendyol Group, and Rumble, etc.	Companies that use Scala language are LinkedIn, Twitter, Coursera, Netflix, Sony, Foursquare and Asana, etc.
