为什么要开源呢？难道因为它是免费的吗？显然并不全是。

首先，让我们来定义一下 “开源” 这个词。简单地说，开源通常是指免费提供原始源代码的软件，并可以重新分发和修改。开源的一个流行说法是，它代表自由和准入，并不意味着是没有成本，因为使用开源工具的责任转移到了负责实施这些工具的开发者身上。这需要理解、经验和时间。

许多为Web应用程序、超级计算机甚至互联网本身提供动力的技术都是开源的。这包括大量的开发工作，如Linux和Node-RED。Node-RED这样的平台正在改变我们对用户界面开发的看法。它为许多想要使用新工具来构建他们的机器可视化，但缺乏编写HTML5或typescript的技能和经验的用户提供了访问权限。

Node-RED是一个低代码量的环境，它使用Node.js，一个基于JavaScript编程语言的运行环境。这个环境使用了HTML5、Vue.js、React.js。它是如此容易使用，以至于开发人员可以在几分钟内完成从互动到概念验证的过程。
