Union Busting

Pass in any number of sets and this package will create a new set containing the union of those sets and then throws all of that away and returns null.

Source Code

module.exports = function(...sets) {
 
    // create a union
    let union = new Set();
    for( let set of sets ) {
        for( let value of set ) {
            union.add(value);
        }
    }
 
    // bust the union
    union = null;
 
    return union;
};

Installation

npm install union-busting

const unionBusting = require("union-busting");
