P5.js由McCarthy和纽约大学ITP以及其他贡献者共同合作开发,它是一个能够处理可视化编程语言的分支,它使非程序开发人员(如艺术家、设计师、教育工作者和初学者等)能够编写JavaScript代码和创建可视化项目。本课程为Daniel Shiffman老师的p5.js教程。原链接在这:https://ww
目前已经被 Chrome、Firefox、Nodejs 支持。 flat & flatmap 等价于 lodashflatten功能: constarray = [1, [2, [3]]]; array.flat();// -> [1, 2, [3]] 还支持自定义深度,如果支持Infinity无限层级: constarray = [1, [2, [3]]]; array.flat(Infinity);// -> [1, 2, 3] 这样我们就可...

怪我怪我,这个报错跟我们的核心内容没关系,还是跨域的问题,我们再给server.js加一行代码: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 constserver=http.createServer((req,res)=>{res.setHeader("Access-Control-Allow-Origin","*");res.setHeader("Access-Control-Allow-Methods","*");res.end("He...
Node.js 是一个基于ChromeV8引擎的JavaScript运行环境。 对于这句描述,没有什么太大的观念。可能是欠缺的基础知识太多了。 简单的说 Node.js 就是运行在服务端的 JavaScript。 Node.js 是一个基于Chrome JavaScript 运行时建立的一个平台。 Node.js是一个事件驱动I/O服务端JavaScript环境,基于Google的V8引擎,V8引...
Added: An API option to provide a custom array of keycodes that will be ignored. Changed: Typing in form fields is no longer filtered out. The data-whatinput attribute immediately reflects the current input. The data-whatintent attribute now takes on the role of remembering mouse input prior...
