method Range.prototype.at

import { Range } from "https://deno.land/x/aitertools@0.6.0/src/range.ts";

at(index: number): T | undefined

Returns the element at the specified index in the range. Note that it guarantees to return the same value as Array.from(range).at(index).

import { range } from "./range.ts";

const r = range(10, -10, -3.5);
console.log(r.at(3), r.at(-1));

The above example will print the following 2 lines:

-0.5
-7.5

Parameters

index: number

The index of the element to return. If it is negative, it counts from the end of the range.

T | undefined

The element at the specified index in the range. If the index is out of range, undefined is returned.
