To use the mean function from the lodash library in TypeScript, you can follow these steps:

1. Install lodash library using npm or yarn:

index.ts
npm install lodash
19 chars
2 lines

2. Import the lodash library in your TypeScript file:

index.ts
import * as _ from 'lodash';
29 chars
2 lines

3. Define an array of numbers:

index.ts
const numbers = [1, 2, 3, 4, 5];
33 chars
2 lines

4. Use the mean function to calculate the mean of the array:

index.ts
const meanValue = _.mean(numbers);
console.log(meanValue); // Output: 3

The mean function from the lodash library calculates the mean value of an array of numbers. It takes an array of numbers as input parameter and returns a number, which is the mean value of the array.
