26 /**
27 * Creates a lodash object which wraps value to enable implicit method chain sequences.
28 * Methods that operate on and return arrays, collections, and functions can be chained together.
29 * Methods that retrieve a single value or may return a primitive value will automatically end the
30 * chain sequence and return the unwrapped value. Otherwise, the value must be unwrapped with value().
31 *
32 * Explicit chain sequences, which must be unwrapped with value(), may be enabled using _.chain.
33 *
34 * The execution of chained methods is lazy, that is, it's deferred until value() is
35 * implicitly or explicitly called.
36 *
37 * Lazy evaluation allows several methods to support shortcut fusion. Shortcut fusion
38 * is an optimization to merge iteratee calls; this avoids the creation of intermediate
39 * arrays and can greatly reduce the number of iteratee executions. Sections of a chain
40 * sequence qualify for shortcut fusion if the section is applied to an array and iteratees
41 * accept only one argument. The heuristic for whether a section qualifies for shortcut
42 * fusion is subject to change.
43 *
44 * Chaining is supported in custom builds as long as the value() method is directly or
45 * indirectly included in the build.
46 *
47 * In addition to lodash methods, wrappers have Array and String methods.
48 * The wrapper Array methods are:
49 * concat, join, pop, push, shift, sort, splice, and unshift.
50 * The wrapper String methods are:
51 * replace and split.
52 *
53 * The wrapper methods that support shortcut fusion are:
54 * at, compact, drop, dropRight, dropWhile, filter, find, findLast, head, initial, last,
55 * map, reject, reverse, slice, tail, take, takeRight, takeRightWhile, takeWhile, and toArray
56 *
57 * The chainable wrapper methods are:
58 * after, ary, assign, assignIn, assignInWith, assignWith, at, before, bind, bindAll, bindKey,
59 * castArray, chain, chunk, commit, compact, concat, conforms, constant, countBy, create,
60 * curry, debounce, defaults, defaultsDeep, defer, delay, difference, differenceBy, differenceWith,
61 * drop, dropRight, dropRightWhile, dropWhile, extend, extendWith, fill, filter, flatMap,
62 * flatMapDeep, flatMapDepth, flatten, flattenDeep, flattenDepth, flip, flow, flowRight,
63 * fromPairs, functions, functionsIn, groupBy, initial, intersection, intersectionBy, intersectionWith,
64 * invert, invertBy, invokeMap, iteratee, keyBy, keys, keysIn, map, mapKeys, mapValues,
65 * matches, matchesProperty, memoize, merge, mergeWith, method, methodOf, mixin, negate,
66 * nthArg, omit, omitBy, once, orderBy, over, overArgs, overEvery, overSome, partial, partialRight,
67 * partition, pick, pickBy, plant, property, propertyOf, pull, pullAll, pullAllBy, pullAllWith, pullAt,
68 * push, range, rangeRight, rearg, reject, remove, rest, reverse, sampleSize, set, setWith,
69 * shuffle, slice, sort, sortBy, sortedUniq, sortedUniqBy, splice, spread, tail, take,
70 * takeRight, takeRightWhile, takeWhile, tap, throttle, thru, toArray, toPairs, toPairsIn,
71 * toPath, toPlainObject, transform, unary, union, unionBy, unionWith, uniq, uniqBy, uniqWith,
72 * unset, unshift, unzip, unzipWith, update, updateWith, values, valuesIn, without, wrap,
73 * xor, xorBy, xorWith, zip, zipObject, zipObjectDeep, and zipWith.
74 *
75 * The wrapper methods that are not chainable by default are:
76 * add, attempt, camelCase, capitalize, ceil, clamp, clone, cloneDeep, cloneDeepWith, cloneWith,
77 * conformsTo, deburr, defaultTo, divide, each, eachRight, endsWith, eq, escape, escapeRegExp,
78 * every, find, findIndex, findKey, findLast, findLastIndex, findLastKey, first, floor, forEach,
79 * forEachRight, forIn, forInRight, forOwn, forOwnRight, get, gt, gte, has, hasIn, head,
80 * identity, includes, indexOf, inRange, invoke, isArguments, isArray, isArrayBuffer,
