Cartesian product of javascript object with different types of values like string, object and array

Question

I am working on an assignment. I have the following object form.

{
    name: \"name here\",
    skills:  [ \"cash\", \"shares\" ],
    subjects: 
    [ 
      {
         


        

Answer 1

You could take a recursive function which separates all key/value pairs and build a new cartesian product by iterating the values, if an array with objects call getCartesian again and build new objects.

The referenced link does not work, because of the given arrays of objects which the linked answer does not respect.

function getCartesian(object) {
    return Object.entries(object).reduce((r, [k, v]) => {
        var temp = [];
        r.forEach(s =>
            (Array.isArray(v) ? v : [v]).forEach(w =>
                (w && typeof w === 'object' ? getCartesian(w) : [w]).forEach(x =>
                    temp.push(Object.assign({}, s, { [k]: x }))
                )
            )
        );
        return temp;
    }, [{}]);
}

var data = { name: "name here", skills: ["cash", "shares"], subjects: [{ subName: "subject1", remark: ['remark1', 'remark2'] }, { subName: "subject2", remark: ['remark1', 'Hockey'] }] };

console.log(getCartesian(data));
