nv-get-random-values

• same as crypto.getRandomValues
• simple wrap of crypto.getRandomValues to avoid : DOMException [QuotaExceededError]: The requested length exceeds 65,536 bytes
• support FloatTypedArray and ArrayBuffer and DataView

install

• npm install nv-get-random-values

usage

  const getRandomValues  = require("nv-get-random-values");
