A JavaScript equivalent of PHP's stream_context_set_params

{% codeblock stream/stream_context_set_params.js lang:js https://raw.github.com/kvz/phpjs/master/functions/stream/stream_context_set_params.js raw on github %}
function stream_context_set_params (stream_or_context, params) {
  // http://kevin.vanzonneveld.net
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // *     example 1: var context = stream_context_create();
  // *     example 1: stream_context_set_params({notification:function (notification_code, severity, message, message_code, bytes_transferred, bytes_max) {}});
  // *     returns 1: true
  var param = '';

  // Docs also allow for "options" as a parameter here (i.e., setting options instead of parameters) and source seems to allow encoding, input_encoding, output_encoding, and default_mode
  for (param in params) { // Overwrites all, or just supplied? Seems like just supplied
    if (param === 'options') {
      stream_or_context.stream_options = params[param]; // Overwrite all?
    } else {
      stream_or_context.stream_params[param] = params[param];
    }
  }
  return true;
