前言:Buffer 模块是 Node.js 非常重要的模块,很多模块都依赖它,本文介绍一下 Buffer 模块底层的原理,包括 Buffer 的核心实现和 V8 堆外内存等内容。...如果长度大于 Node.js 设置的阈值,则调用 createFromString 通过 C++ 层直接分配内存。2. 否则判断之前剩下的内存是否足够,足够则直接分配。...Node.js 初始...
要将字符串转换为字节数组,可以使用Buffer.from()方法。这个方法接受两个参数,第一个参数是要转换的字符串,第二个参数是指定字符串的编码方式,默认为utf8编码。 下面是一个示例代码: 代码语言:txt 复制 const str = 'Hello, world!'; const buf = Buffer.from(str, 'utf8'); console.log(buf); 输...

to convert this HMAC_SHA256 to WebCrypto API, I found this code snippet, I am passing the secret as a string but can't make exact same output, so I see the difference is here crypto-js is converting secret input with CryptoJS.enc.Base64.parse(secret) which gets a WordArray, Not sur...
除了Object类型之外,Array类型恐怕是js中最常用的类型了,并且随着js的发展进步,数组中提供的方法也越来越来,对数组的处理也出现了各种骚操作。 如果对js原型/原型链不了解的可以移步_深入了解javascript原型/原型链,_下面我们就来一起学习下js的数组。
