how to use the first function from lodash in javascript

To use the first function from the Lodash library in JavaScript, first you will need to import it into your code.

You can do this by installing Lodash via npm or yarn:

index.tsx
npm install lodash
19 chars
2 lines

or

index.tsx
yarn add lodash
16 chars
2 lines

Then, in your JavaScript file, you can import the first function from Lodash like this:

index.tsx
import { first } from 'lodash';
32 chars
2 lines

Once you have imported the first function, you can use it to return the first element of an array like this:

index.tsx
const myArray = [1, 2, 3];
const firstElement = first(myArray);
console.log(firstElement); // Output: 1
104 chars
4 lines

Alternatively, you can also use the array method slice() to achieve the same result:

index.tsx
const myArray = [1, 2, 3];
const firstElement = myArray.slice(0, 1);
console.log(firstElement); // Output: [1]
