如何在Javascript中使ArrayBuffer不可变？

Question

如何在Javascript中使import csv with open("hisEasyR.txt", "a") as hisEasyRFile: writer = csv.writer(hisEasyRFile, delimiter='|') writer.writerows(results) 不可变的内容？ |方法似乎不起作用。有没有办法实现呢？它会成为可能吗？

您可以将ArrayBuffer转换为使用data URI定义的const不可变字符串

const reader = new FileReader;

reader.onload = () => { const ab = reader.result // `ab` cannot be changed }

reader.readAsDataURL(new ArrayBuffer(123));
