NodeJS how to setup Lodash

by

In Node.js, you can import and use the Lodash library to work with arrays, objects, functions, and other data types. Here’s an example of how to import Lodash in Node.js:

Install Lodash:


npm install lodash
Create a JavaScript file, for example, example.js, and open it in a text editor.

Import Lodash into your file:


const _ = require(‘lodash’);
Now you can use any of the Lodash functions in your code. Here’s an example that uses the map function from Lodash to double each element in an array:


const numbers = [1, 2, 3, 4, 5];
const doubledNumbers = _.map(numbers, (num) => num * 2);
console.log(doubledNumbers);
The output will be:


[2, 4, 6, 8, 10]
In this example, we import Lodash using require(‘lodash’) and assign it to the variable . Then we use the .map function to iterate over each element in the numbers array and double them.

Make sure you have installed Lodash using npm (npm install lodash) before running the code.
