        /**
        * Creates a lodash object which wraps value to enable implicit method chain sequences.
        * Methods that operate on and return arrays, collections, and functions can be chained together.
        * Methods that retrieve a single value or may return a primitive value will automatically end the
        * chain sequence and return the unwrapped value. Otherwise, the value must be unwrapped with value().
        *
        * Explicit chain sequences, which must be unwrapped with value(), may be enabled using _.chain.
        *
        * The execution of chained methods is lazy, that is, it's deferred until value() is
        * implicitly or explicitly called.
        *
        * Lazy evaluation allows several methods to support shortcut fusion. Shortcut fusion
        * is an optimization to merge iteratee calls; this avoids the creation of intermediate
        * arrays and can greatly reduce the number of iteratee executions. Sections of a chain
        * sequence qualify for shortcut fusion if the section is applied to an array and iteratees
        * accept only one argument. The heuristic for whether a section qualifies for shortcut
        * fusion is subject to change.
        *
        * Chaining is supported in custom builds as long as the value() method is directly or
        * indirectly included in the build.
        *
        * In addition to lodash methods, wrappers have Array and String methods.
        * The wrapper Array methods are:
        * concat, join, pop, push, shift, sort, splice, and unshift.
        * The wrapper String methods are:
        * replace and split.
        *
        * The wrapper methods that support shortcut fusion are:
        * at, compact, drop, dropRight, dropWhile, filter, find, findLast, head, initial, last,
        * map, reject, reverse, slice, tail, take, takeRight, takeRightWhile, takeWhile, and toArray
        *
        * The chainable wrapper methods are:
        * after, ary, assign, assignIn, assignInWith, assignWith, at, before, bind, bindAll, bindKey,
        * castArray, chain, chunk, commit, compact, concat, conforms, constant, countBy, create,

        * push, range, rangeRight, rearg, reject, remove, rest, reverse, sampleSize, set, setWith,
        * shuffle, slice, sort, sortBy, sortedUniq, sortedUniqBy, splice, spread, tail, take,

        * xor, xorBy, xorWith, zip, zipObject, zipObjectDeep, and zipWith.
