Hello World Created

Hellow World 的不同语言实现方法，值得了解

我们作为一名程序员，在学习不同语言时至少完成了一个“Hello, World!“程序。当我们学习一门新的语言时，“Hello, World!“通常是我们所写的第一个程序。然而学会（了解）不同语言的表达是一个程序猿所必要的，在这里我询问大家，大家从学习编程语言以来，目前能使用多少种语言的基础表达呢？欢迎大家评论区域留言讨论哦。

在这里，我会带大家经历`一段计算机编程领域的时空之旅。为此，我将向你展示50种不同的编程语言的 “Hello, World!“程序的写法。如果有错也请大家评论区去纠正呢。毕竟在下也不是十分了解。

总结一下，50种语言的发展来看，大多数语言的设计思想都是互相借鉴的。语言的发展也是逐渐演进的，但不是越强大的语言就越流行。一门语言想要变得流行也是需要一定的机遇的（例如Python），或者是需要有个优质的大腿（例如Java和Dart）。(如果以上代码有问题或者有错的请大家评论区帮忙纠正）
