今天早上看到微博上喵大 @onevcat 在吐槽这段代码
https://github.com/ParsePlatform/parse-server/blob/master/RestWrite.js#L704-L715
// Returns a string that's usable as an object id.
// Probably unique. Good enough? Probably!
function newObjectId() {
var chars = ('ABCDEFGHIJKLMNOPQRSTUVWXYZ' +
'abcdefghijklmnopqrstuvwxyz' +
'0123456789');
var objectId = '';
for (var i = 0; i < 10; ++i) {
objectId += chars[Math.floor(Math.random() * chars.length)];
}
return objectId;
}
如果大家来写这一段代码应该会怎样写？
