Function baseIteratee

underscore-node-f.cjs:760–765

(value, context, argCount)

// element in a collection, returning the desired result — either `_.identity`,
// an arbitrary callback, a property matcher, or a property accessor.
function baseIteratee(value, context, argCount) {
  if (value == null) return identity;
  if (isFunction$1(value)) return optimizeCb(value, context, argCount);
  if (isObject(value) && !isArray(value)) return matcher(value);
  return property(value);
}

// External wrapper for our callback generator. Users may customize
// `_.iteratee` if they want additional predicate/iteratee shorthand styles.
