TypedArray.prototype.toLocaleString()

TypedArray 实例的 toLocaleString() 方法返回一个表示类型化数组元素的字符串。使用 toLocaleString 方法将元素转换为字符串，并且这些字符串由特定于区域设置的字符串（例如逗号 ","）分隔。该方法与 Array.prototype.toLocaleString() 的算法相同。

¥The toLocaleString() method of TypedArray instances returns a string representing the elements of the typed array. The elements are converted to strings using their toLocaleString methods and these strings are separated by a locale-specific string (such as a comma ","). This method has the same algorithm as Array.prototype.toLocaleString().

使用 toLocaleString()

¥Using toLocaleString()

js
const uint = new Uint32Array([2000, 500, 8123, 12, 4212]);
