at

Gets the elements at specified indices from an array and returns a new array.

const result = at(arr, indices);

Reference

at(arr, indices)

Use at when you want to select elements at specific positions from an array. You can use negative indices to select elements from the end of the array.

import { at } from 'es-toolkit/array';

// Get elements at multiple indices from a number array.
at([10, 20, 30, 40, 50], [1, 3, 4]);
// Returns: [20, 40, 50]

// Use negative indices to get elements from the end.
at(['a', 'b', 'c', 'd'], [0, -1, -2]);
// Returns: ['a', 'd', 'c']

Non-integer indices are converted to integers.

import { at } from 'es-toolkit/array';

at([1, 2, 3, 4], [1.5, 2.9]); // [2, 3]

Parameters

• arr (T[]): The array to get elements from.
• indices (number[]): An array of indices of the elements to get. Negative values count from the end of the array.

Returns

(T[]): A new array containing the elements at the specified indices.
