### customUtilsNode.uid(len) ⇒ <code>string</code>
|
|
|
|
|
<p>Return a random alphanumerical string of length len
|
|
|
|
|
There is a very small probability (less than 1/1,000,000) for the length to be less than len
|
|
|
|
|
(il the base64 conversion yields too many pluses and slashes) but
|
|
|
|
|
that's not an issue here
|
|
|
|
|
The probability of a collision is extremely small (need 3*10^12 documents to have one chance in a million of a collision)
