@文心快码nodejs string转int 文心快码 在Node.js中,将字符串(string)转换为整数(int)可以使用JavaScript内置的Number函数或parseInt函数。以下是详细的解释和代码示例: 1. 确定转换方法 在Node.js环境中,转换字符串为整数主要有两种方法: 使用Number函数。 使用parseInt函数。 2. 使用Number函数或parseInt函数进行转换...
3. ArrayBuffer 和 TypedArray TypedArray: Unit8Array, Int32Array这些都是TypedArray, 那些 Uint32Array 也好,Int16Array 也好,都是给 ArrayBuffer 提供了一个 “View”,MDN上的原话叫做 “Multiple views on the same data”,对它们进行下标读写,最终都会反应到它所建立在的 ArrayBuffer 之上。 ArrayBuffer 本身只...
