Function cb

underscore.js:784–787

(value, context, argCount)

  // The function we call internally to generate a callback. It invokes
  // `_.iteratee` if overridden, otherwise `baseIteratee`.
  function cb(value, context, argCount) {
    if (_$1.iteratee !== iteratee) return _$1.iteratee(value, context);
    return baseIteratee(value, context, argCount);
  }

  // Returns the results of applying the `iteratee` to each element of `obj`.
  // In contrast to `_.map` it returns an object.
