const wait_while = require('@vbarbarosh/node-helpers/src/wait_while');
array_chunk([1, 2, 3, 4, 5], 2); // [[1, 2], [3, 4], [5]]
items.sort(fcmpx(['-age', 'name'])); // age desc, then name asc
await fs_tempdir(async function (d) {
// ... `d` is removed after this function settles
});
const json = await http_get_json('https://api.example.com/items');
