Why Lodash ?
It provides various inbuilt functions for collections, arrays, to manipulate objects, and other utility methods that we can use directly instead of writing them from scratch. It makes it easier to iterate over the arrays, strings as well as objects. Its modular methods enable the creation of composite functions easier.
Installation: It can be used directly using the CDN link or can be installed using npm or yarn.
Method 1: We can directly use the file in the browser. Go to the official documentation and copy the lodash.min.js file CDN link and paste this link inside the head section.
Method 2: We can install it with npm. Make sure that you have Node.js and npm installed.
npm install lodash
If you are using yarn then you can use the following command:
yarn install lodash
Now in order to use the Lodash library, you need to require it in the code file.
const _ = require("lodash");
Now let’s understand how to use Lodash with the help of the code example.
Example: In this example, we will simply create an empty string using the lodash _.stubString() method.
// Requiring the lodash library const _ = require("lodash"); // Use of _.stubString() method // to create an empty String let mystring = _.stubString(); // Printing the output console.log(mystring);
"" Empty String
