how to use the last function from the lodash library in typescript

To use the last function from the lodash library in TypeScript, you will need to first import the lodash library and then use the last function from the imported lodash library. Here is an example code snippet:

index.ts
import * as _ from 'lodash';

const myArray: number[] = [1, 2, 3, 4, 5];
const lastItem: number = _.last(myArray);
console.log(lastItem); // output: 5

In this example, we first import the entire lodash library using the import statement. Then, we create an array of numbers called myArray. We use the last function from the lodash library to get the last item in the myArray array and store it in a variable called lastItem. Finally, we log the value of lastItem.

Make sure that you have lodash properly installed in your project before using it. You can install it using npm:

index.ts
npm install lodash --save
