**Lodash** is a JavaScript library that provides utility functions for common programming tasks using a *functional programming paradigm*; it builds upon the older *underscore.js* library. 

Lodash has several built-in utility functions that make coding in JavaScript easier and cleaner. Instead of writing common functions, again and again, the task can be accomplished with a single line of code.


# Installation

Lodash can be installed via NPM:
```
npm install --save lodash
```
After installation is complete, Lodash can be imported into a JavaScript file as:
```javascript
import _ from "lodash"
```
Now, all of Lodash's functions can be accessed by the underscore operator.

# Functions 
Some handy functions included in Lodash are:

## `_.concat()`
The **`_.concat()` function**​ simply concatenates values to an existing array, as shown below:

let arr = ['dog', 'cat', 'bird', 'hamster']
let arr = _.concat(arr, 'zebra', 'snake');
// Output => arr = ['dog', 'cat', 'bird', 'hamster', 'zebra', 'snake']

## `_.find()`
Instead of using a loop to iterate through an array to search for an object, the **`_.find()` function** can perform the same task in a single line. Moreover, it can be used to find an object using multiple properties.

## `_.intersection`
The normal code, to find the common elements between two arrays, uses a for loop with several lines of code. In Lodash, this is achieved in a single line with the **`_.intersection()` function**:

let arr1 = ["football", "cricket", "tennis", "squash"]
let arr2 = ["cricket", "rugby", "badminton", "tennis"]

let commonElements = _.intersection(arr1, arr2);
// commonElements-> ["cricket", "tennis"]
