How to model nested Array Data Structure of primitive Types

Question

I need to model a nested data structure with an array of an array of numbers. Ex:

"measures": [
  [1, 91.3],
  [2, 87.5],
  ...

I tried like this:

"mmeasures": {
  "type": [ [ "Number" ] ]
},

But it does not seem to work.

The corresponding loopback docs do not mention nested arrays.

Hi, Can you explain the business case you need this? It could be the case that a simply using and object with an array { [ ] } , could do the trick. Or maybe you need a matrix? [ ] [ ] . Other possibility to consider would be to use constructor i.e - let myArrOfArr = new Array(new Array( )); — groo

I think the business case does not matter at all here, I asked a clear question. The matrix solution also does not work as it is not even valid JS. — vanthome

Hi, so.. did you notice in my previous comment the part "It could be the case that a simply using and object with an array { [ ] } , could do the trick" that was exactly the solution you published as valid below :) . Asking about the business case I was just trying to understand to see if that would fit the case. — groo

No it isn't the solution. I'm simply not using an object, neither in the model nor in the real data. — vanthome

Hi, humm.. it looks like you're missing basic concepts of javascript, please check this sources and you'll possibly understand: stackoverflow.com/questions/1828924/… eloquentjavascript.net/04_data.html — groo

An array of any typed values did the trick:

"mmeasures": {
  "type": [ "any" ]
},
