-
-In Node.js:
-```js
-// Load the full build.
-var _ = require('lodash');
-// Load the core build.
-var _ = require('lodash/core');
-// Load the FP build for immutable auto-curried iteratee-first data-last methods.
-var fp = require('lodash/fp');
-
-// Load method categories.
-var array = require('lodash/array');
-var object = require('lodash/fp/object');
-
-// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
-var at = require('lodash/at');
-var curryN = require('lodash/fp/curryN');
-```
-
-See the [package source](https://github.com/lodash/lodash/tree/4.17.19-npm) for more details.
-
-**Note:**<br>
-Install [n_](https://www.npmjs.com/package/n_) for Lodash use in the Node.js < 6 REPL.

-   * Creates a `lodash` object which wraps `value` to enable implicit method

-   * 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`

-   * `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`,

- * is invoked more than once during the `wait` timeout.

-     * 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.

-     * delayed `func` invocations and a `flush` method to immediately invoke them.
-     * Provide `options` to indicate whether `func` should be invoked on the
-     * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
-     * with the last arguments provided to the debounced function. Subsequent
-     * calls to the debounced function return the result of the last `func`
-     * invocation.
-     *
-     * **Note:** If `leading` and `trailing` options are `true`, `func` is
-     * invoked on the trailing edge of the timeout only if the debounced function
-     * is invoked more than once during the `wait` timeout.
-     *
-     * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
-     * until to the next tick, similar to `setTimeout` with a timeout of `0`.

- * Creates a `lodash` object which wraps `value` to enable implicit method

- * 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`
