how to use the times function from lodash in javascript

The times method from lodash can be used to create an array of a given length with a specified value or with the results of a function.

To use it, you first need to import it from lodash:

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

Then you can use it like this:

index.tsx
// create an array with 5 undefined elements
const arr1 = times(5);

// create an array with 3 elements, each with the value 0
const arr2 = times(3, () => 0);

// create an array with 4 elements, each with the result of a function
const arr3 = times(4, (index) => index * 2);
276 chars
9 lines

The first argument to times specifies the length of the array to create.

The second argument is optional. If it is not provided or undefined, the array elements will be undefined. If it is a value (not a function), each element will have that value. If it is a function, it will be called for each element with the current index as its argument and its return value will be the value of that element.
