        /**
        * Creates a lodash object which wraps the given value to enable intuitive method chaining.
        *
        * In addition to Lo-Dash methods, wrappers also have the following Array methods:
        * concat, join, pop, push, reverse, shift, slice, sort, splice, and unshift
        *
        * Chaining is supported in custom builds as long as the value method is implicitly or
        * explicitly included in the build.
        *
        * The chainable wrapper functions are:
        * after, assign, bind, bindAll, bindKey, chain, chunk, compact, compose, concat, countBy,
        * createCallback, curry, debounce, defaults, defer, delay, difference, filter, flatten,
        * forEach, forEachRight, forIn, forInRight, forOwn, forOwnRight, functions, groupBy,
        * indexBy, initial, intersection, invert, invoke, keys, map, max, memoize, merge, min,
        * object, omit, once, pairs, partial, partialRight, pick, pluck, pull, push, range, reject,
        * remove, rest, reverse, sample, shuffle, slice, sort, sortBy, splice, tap, throttle, times,
        * toArray, transform, union, uniq, unshift, unzip, values, where, without, wrap, and zip
        *
        * The non-chainable wrapper functions are:
        * clone, cloneDeep, contains, escape, every, find, findIndex, findKey, findLast,
        * findLastIndex, findLastKey, has, identity, indexOf, isArguments, isArray, isBoolean,
        * isDate, isElement, isEmpty, isEqual, isFinite, isFunction, isNaN, isNull, isNumber,
        * isObject, isPlainObject, isRegExp, isString, isUndefined, join, lastIndexOf, mixin,
        * noConflict, parseInt, pop, random, reduce, reduceRight, result, shift, size, some,
        * sortedIndex, runInContext, template, unescape, uniqueId, and value
        *
        * The wrapper functions first and last return wrapped values when n is provided, otherwise
        * they return unwrapped values.
        *
        * Explicit chaining can be enabled by using the _.chain method.
