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

To use the reverse function from Lodash library in Typescript, you need to first install the Lodash library using npm package manager by running the npm install lodash command. After installing the library, you can import the reverse function and use it in your code.

Here's an example of how to use the reverse function:

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

const arr: number[] = [1, 2, 3, 4, 5];
const reversedArr: number[] = _.reverse(arr);

console.log(reversedArr); // [5, 4, 3, 2, 1]

In the above example, we imported the Lodash library using the import statement and assigned it to the _ variable. We then declared an array of numbers and passed it to the reverse function, which returns the reversed array. The reversed array is then logged to the console.

Additionally, if you are using Typescript, you can also install the @types/lodash package to get the type definitions for Lodash. This will help with better autocompletion and error checking in your code.

npm install @types/lodash

With that installed, you can use the reverse function with the correct types:

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

const arr: number[] = [1, 2, 3, 4, 5];
const reversedArr: number[] = _.reverse<number>(arr); // type of return value inferred

console.log(reversedArr); // [5, 4, 3, 2, 1]
