Random strings joined with += and .join() (v11)

Revision 11 of this benchmark created on

Setup

function randomString(length) {
  const chars =
    "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
  let result = "";
  for (let i = 0; i < length; i++) {
    result += chars.charAt(Math.floor(Math.random() * chars.length));
  }
  return `${result.substring(0)}`;
}

var randomStrings = Array.from({ length: 50 }, () => randomString(10+Math.floor(Math.random()*500)));
