David Glasser 43b4b30205 Release PLUGINS-PREVIEW@1
This included removing some internal version constraints. It would be
nice if package A could say "use B@2.0.0" (when both have changed), but
when they're both in the release, we need to make a release that has a
B@2.0.0-rc in it, which doesn't match that constraint. Fortunately,
constraints aren't necessary within a release anyway.

random

The random package provides several functions for generating random numbers. It uses a cryptographically strong pseudorandom number generator when possible, but falls back to a weaker random number generator when cryptographically strong randomness is not available (on older browsers or on servers that don't have enough entropy to seed the cryptographically strong generator).

  • Random.id([n]) - Returns a unique identifier, such as "Jjwjg6gouWLXhMGKW", that is likely to be unique in the whole world. The optional argument n specifies the length of the identifier in characters and defaults to 17.

  • Random.secret([n]) - Returns a random string of printable characters with 6 bits of entropy per character. The optional argument n specifies the length of the secret string and defaults to 43 characters, or 256 bits of entropy. Use Random.secret for security-critical secrets that are intended for machine, rather than human, consumption.

  • Random.fraction() - Returns a number between 0 and 1, like Math.random.

  • Random.choice(arrayOrString) - Returns a random element of the given array or string.

  • Random.hexString(n) - Returns a random string of n hexadecimal digits.
