-/**
- * Creates a duplicate-value-free version of an array using `SameValueZero`
- * for equality comparisons. Providing `true` for `isSorted` performs a faster
- * search algorithm for sorted arrays. If an iteratee function is provided it
- * is invoked for each value in the array to generate the criterion by which
- * uniqueness is computed. The `iteratee` is bound to `thisArg` and invoked
- * with three arguments; (value, index, array).
- *
- * If a property name is provided for `predicate` the created `_.property`
- * style callback returns the property value of the given element.
- *
- * If a value is also provided for `thisArg` the created `_.matchesProperty`
- * style callback returns `true` for elements that have a matching property
- * value, else `false`.
- *
- * If an object is provided for `predicate` the created `_.matches` style
- * callback returns `true` for elements that have the properties of the given
- * object, else `false`.
- *
- * **Note:** `SameValueZero` comparisons are like strict equality comparisons,
- * e.g. `===`, except that `NaN` matches `NaN`. See the
- * [ES spec](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-samevaluezero)

- * Creates a `lodash` object which wraps `value` to enable implicit chaining.
- * Methods that operate on and return arrays, collections, and functions can
- * be chained together. Methods that return a boolean or single value will
- * automatically end the chain returning the unwrapped value. Explicit chaining
- * may be enabled using `_.chain`. The execution of chained methods is lazy,
- * that is, execution is deferred until `_#value` is implicitly or explicitly
- * called.
- *
- * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
- * fusion is an optimization that merges iteratees to avoid creating intermediate
- * arrays and reduce the number of iteratee executions.
- *
- * 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 also have the following `Array` methods:
- * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
- * and `unshift`
- *
- * The wrapper methods that support shortcut fusion are:
- * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
- * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
- * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
- * and `where`
- *
- * The chainable wrapper methods are:
- * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
- * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
- * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
- * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
- * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
- * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
- * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
- * `keysIn`, `map`, `mapValues`, `matches`, `matchesProperty`, `memoize`, `merge`,
- * `mixin`, `negate`, `noop`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
- * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,

- * `unshift`, `unzip`, `values`, `valuesIn`, `where`, `without`, `wrap`, `xor`,
- * `zip`, and `zipObject`
- *
- * The wrapper methods that are **not** chainable by default are:
- * `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
- * `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
- * `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,
