Correctly grouping members within modules in JSDoc v3

JSDoc is great! It's documentation not so much. I needed a way to logically group together global methods and I was unsuccessful in finding a straightforward way in its official documentation.

Eventually, I've come across the following method, using @module and @member.

First, we define the module name, usually at the top of the file:

@module MyModule

We then proceed to annotate the target function with @memeber MyModule. One other important aspect is to also include @function along with the name of the function in order to appear in the module section.

/**
 * @member MyModule
 * @function myFunction
 ....
 */
 export const myFunction = () => ....

Postman Automatic Auth Token

Postman can run JavaScript commands when executing a request. These commands can be placed in the "Tests" tab inside a request. For example, to automatically set a token as a collection variable, the following commands are used:

var auth = pm.response.headers.get("Authorization");
pm.collectionVariables.set('token', auth.split(" ")[1]);

The Docs regarding Postman scripting can be found here:

Using destructuring assignment to dynamically create new functions in JavaScript

// www.codewars.com/kata/525f3eda17c7cd9f9e000b39

const curry = (operand, operator) => (!operator) ? operand : operator(operand);

const [zero, one, two, three, four, five, six, seven, eight, nine] =
  [0,1,2,3,4,5,6,7,8,9].map(operand => ((operator) => curry(operand, operator)));

const plus = (first) => (second) => second + first;
const minus = (first) => (second) => second - first;
const times = (first) => (second) => second * first;
const dividedBy = (first) => (second) => Math.floor(second / first);
