Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

• Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
• Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
• If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
• If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

/**
 * Script loading is difficult thanks to IE. We need callbacks to fire
 * immediately following the script's execution, with no other scripts
 * running in between. If other scripts on the page are able to run
 * between our script and its callback, bad things can happen, such as
 * `jQuery.noConflict` not being called in time, resulting in plugins
 * latching onto our version of jQuery, etc.
 *
 * For IE<10 we use a relatively well-documented 'preloading' strategy,
 * which ensures that the script is ready to execute *before* appending

# Usage: watch PATH COMMAND...

# This script watches PATH and runs COMMAND whenever PATH or a descendent

# If PATH is "-", then the list of paths comes from standard input.
