assertEquals(isscalar(2), true);

import { assertEquals } from "jsr:@std/assert";

assertEquals(isscalar([2]), true);

import { assertEquals } from "jsr:@std/assert";

assertEquals(isscalar([[2]]), true);

import { assertEquals } from "jsr:@std/assert";

assertEquals(isscalar([1, 2, 3]), false);

import { assertEquals } from "jsr:@std/assert";

assertEquals(isscalar([[1, 2], [3, 4]]), false);

import { assertEquals } from "jsr:@std/assert";
