/**
 * An alternative to `reduce`; this method transforms `object` to a new `accumulator` object which is the result of running each of its own enumerable string keyed properties thru `iteratee`, with each invocation potentially mutating the `accumulator` object. If `accumulator` is not provided, a new plain object (`{}`) will be used. Iteratee functions may exit iteration early by explicitly returning `false`.
 *
 * Differences from lodash:
 * - the default accumulator will not have any special prototype, it will simply be `{}`
 * - does not treat sparse arrays as dense
 *
 * Contribution to minified bundle size, when it is the only function imported:
 * - Lodash: 14,240 bytes
 * - Micro-dash: 256 bytes
