how to use the head function from lodash in javascript

To use the head function from lodash in JavaScript, you first need to install lodash by running the following command in your terminal:

index.tsx
npm install lodash

2 lines

Once installed, you can import the head method from lodash in your JavaScript file as shown below:

index.tsx
const _ = require('lodash');

const array = [1, 2, 3, 4, 5];

const firstElement = _.head(array);

console.log(firstElement); // Output: 1

In the code above, we imported the head method from lodash and assigned it to the variable _. We then created an array and assigned it to a variable called array. Finally, we called the head method and passed in the array and assigned the returned value to a variable called firstElement.

The console.log() function then outputs 1 which is the first element of the array.

The head method returns undefined if the array is empty, so it's important to always check whether the array has any elements before calling the method.
