Overview

The Source Academy allows programmers to import functions and constants from a module, using JavaScript's import directive. For example, the programmer may decide to import the function thrice from the module repeat by starting the program with

import { thrice } from "repeat";
Copy

When evaluating such a directive, the Source Academy looks for a module with the matching name, here repeat, in a preconfigured modules site. The Source Academy at https://sourceacademy.org uses the default modules site (located at https://source-academy.github.io/modules).

After importing functions or constants from a module, they can be used as usual.

thrice(display)(8); // displays 8 three times
Copy

if thrice is declared in the module repeat as follows:

const thrice = f => x => f(f(f(x)));
Copy

List of modules available at the default modules site.
