I have two arrays with ids that have linked lengths. By linked lengths I mean that if ArrayA has length = 4 then ArrayB will have the length equal with (ArrayA.length * (ArrayA.length - 1)) / 2 (which means if ArrayA has length = 4 then ArrayB length = 6, if ArrayA has length = 5 then ArrayB length = 10 and so on).
So let’s say these are my arrays: ArrayA = [1, 2, 3, 4] and ArrayB = [a, b, c, d, e, f].
I have to create a new array of arrays based on the next logic:
In the end the new array should look as it follows, where the second parameter is a value from the first array and the third parameter is a value from the second array:
[
[uuidv4(), 1, a],
[uuidv4(), 2, a],
[uuidv4(), 1, b],
[uuidv4(), 3, b],
[uuidv4(), 1, c],
[uuidv4(), 4, c],
[uuidv4(), 2, d],
[uuidv4(), 3, d],
[uuidv4(), 2, e],
[uuidv4(), 4, e],
[uuidv4(), 3, f],
[uuidv4(), 4, f]
]
In the end, I should return this kind of array no matter the size of the arrays, but the arrays have some kind of linked length.
I can’t do this with a simple mapping because I don’t know how to achieve this kind of logic.
Thank you for your time! If something is unclear, I’ll try to explain better.
