How do you define a an array of objects within an array in typescript

Question

So if you want to define a array of objects you would do this:

public racks: Rack[];

However, I want to able to make an array that takes in more arrays of racks so for example,

[ 
  [rack1, rack2, rack3], 
  [rack4, rack5, rack6], 
  [rack7] 
]

My question is how do I define it so it can accept this kind of variable?

You could define an array of arrays of Rack :

public racks: Rack[][];

you're looking for:

public racks: Array<Array<Rack>>;

or less verbose:

public racks: Rack[][];
