+# lodash v4.17.18
+
+The [Lodash](https://lodash.com/) library exported as [Node.js](https://nodejs.org/) modules.
+
+## Installation
+
+Using npm:
+```shell
+$ npm i -g npm
+$ npm i --save lodash
+```
+
+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/4.17.18-npm) for more details.
+
+**Note:**
+Install [n_](https://www.npmjs.com/package/n_) for Lodash use in the Node.js < 6 REPL.
+
+## Support
+
+Tested in Chrome 74-75, Firefox 66-67, IE 11, Edge 18, Safari 11-12, & Node.js 8-12.
+Automated [browser](https://saucelabs.com/u/lodash) & [CI](https://travis-ci.org/lodash/lodash/) test runs are available.

+ * 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`,
