Array manipulation

Lodash provides a wide range of functions to manipulate arrays. The example demonstrates reversing an array.

import _ from 'lodash';

const array = [1, 2, 3, 4, 5];
const reversedArray = _.reverse(array);
console.log(reversedArray); // [5, 4, 3, 2, 1]

Object manipulation

Lodash allows for easy manipulation of objects, such as inverting keys and values in an object.

import _ from 'lodash';

const object = { 'a': 1, 'b': 2 };
const invertedObject = _.invert(object);
console.log(invertedObject); // { '1': 'a', '2': 'b' }

Collection iteration

Lodash provides functions like _.filter for iterating over collections and filtering them based on a condition.

import _ from 'lodash';

const users = [
  { 'user': 'barney', 'age': 36, 'active': true },
  { 'user': 'fred',   'age': 40, 'active': false }
];

const activeUsers = _.filter(users, (user) => user.active);
console.log(activeUsers); // [{ 'user': 'barney', 'age': 36, 'active': true }]
