关于javascript:2020年末记随笔

每个公司都青睐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，也能编写简单的 Java 程序的程序员，的确相当有价值。所以实际上，对于高级开发者来说，学习不止一种编程语言，简直就是必然的要求。
目前而言，面试官越来越看重那些领有多种编程语言教训的工程师。比方，同时有 C ++ 和 Java 的教训就很不错，Python 和 Java 也是。我集体喜爱那些在 C ++ 或者 Java 方面有着丰盛教训，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疾速搞定一些专有工作。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件。

为什么我在文章中抉择上面 5 种语言呢？简略理论。我是基于这些语言的用处、编程范式和风行度及代表性来抉择的。
例如，如果你想找一份利用开发的工作，就不能漠视 Java。同样，做与 web 相干的事件，就得晓得无处不在的 JavaScript。
在开发者职业生涯的晚期，我强烈建议学习 C 语言。它能帮忙开发者贴近零碎底层，通晓那些编程的要害概念，这是暗藏在 JVM 或 CLR 底下的货色。
对于脚本语言，我的抉择是 Python，只管你也可用 Perl 或 Groovy 代替。但在扩大反对方面来看，Python 的体现无疑是最棒的。有很多 Python 模块可供选择，帮你能分分种搞定各种工作。
