That creates an entire extra list of garbage.

    const mapNodeList = (...nodeList) => nodeList.map(myFn);
    mapNodeList(...$nodeList)

Garbage collection really isn't the biggest of concerns here considering this code is susceptible to a stack overflow...

Those aren't the same types. One is a DOM array and the other is a JS array. They don't share the same constructor or the same prototype chain.
