Pass arguments to function without spread (IE11)

Question

Imagine I have the following code:

function log(level, message) {
  console.log(level + " " + message);
}

function supplyToLogger() {
  log(...arguments);
}

supplyToLogger("WARN", "This is a warning.");

How can I supply the arguments object to the log function without the spread operator? I need this to work in IE11, without the use of polyfills.

Like this:

function log(level, message) {
  console.log(level + " " + message);
}

function supplyToLogger() {
  log.apply(null, arguments);
}

supplyToLogger("WARN", "This is a warning.");
