因此,需要注意的是:用ArrayBuffer 作为构造函数的参数时,Uint8Array直接引用这个ArrayBuffer对象作为内部缓冲,而不再创建内部ArrayBuffer对象。 四、Uint8Array 与 String 互转 1、字符串转Uint8Array function stringToUint8Array(str){vararr =[];for(vari =0, j = str.length; i < j; ++i) { arr.push(...

Returnstrueif the input array is byte-wise equal to this array. This method makes a byte-wise comparison of the underlying arrays. Therefore, arrays of the same type should be compared. Arrays of different types will not in general be equal, even if they are initialized with the same data...
Array.prototype.split()并不是 JavaScript 中数组的一个方法。你可能混淆了String.prototype.split()方法,该方法用于将字符串分割成子字符串数组。 基础概念 String.prototype.split()方法通过指定的分隔符将一个字符串分割成多个子字符串,并返回这些子字符串组成的数组。如果没有指定分隔符,则整个字符串会被当作一...

reduce() 方法对数组中的每个元素按序执行一个提供的 reducer 函数,每一次运行 reducer 会将先前元素的计算结果作为参数传入,最后将其结果汇总为单个返回值。
