A utility for enhancing functions by binding default values to their first parameter

function bindDefaults(originalFunction, defaults) {
  const originalFunctionName = originalFunction.name;
  const boundFunction = function (options, ...args) {
    const mergedOptions = Object.assign({}, defaults, options);
    return originalFunction.call(this, mergedOptions, ...args);
  };
  Object.defineProperty(boundFunction, 'name', {
    value: originalFunctionName
  });
  return boundFunction;
}

export { bindDefaults };
