每个公司都喜爱精通多种编程语言并且多才多艺的程序员。一个既能很麻利地写脚本，也能编写复杂的Java程序的程序员，确实相当有价值。所以实际上，对于高级开发者来说，学习不止一种编程语言，几乎就是必然的要求。
目前而言，面试官越来越看重那些拥有多种编程语言经验的工程师。比如，同时有C++ 和Java的经验就很不错，Python和Java也是。我个人喜欢那些在C++ 或者Java方面有着丰富经验，而且能用Groovy、Perl或Python写脚本的软件工程师。
很多时候，写一个小脚本就足以快速搞定一些专有任务。我不想我的程序员们花上一整天用Java去写一个读取CSV文件的程序，或者在TCP/UDP端口抓取信息的程序，这是很浪费时间的一件事情。
为什么我在文章中选择下面5种语言呢？简单实际。我是基于这些语言的用途、编程范式和流行度及代表性来选择的。
例如，如果你想找一份应用开发的工作，就不能忽视Java。同样，做与web相关的事情，就得知道无处不在的JavaScript。
在开发者职业生涯的早期，我强烈建议学习C语言。它能帮助开发者贴近系统底层，知晓那些编程的关键概念，这是隐藏在JVM或CLR底下的东西。
对于脚本语言，我的选择是Python，尽管你也可用Perl或Groovy代替。但在扩展支持方面来看，Python的表现无疑是最棒的。有很多Python模块可供选择，帮你能分分种搞定各种任务。
