Fill
, a common JavaScript function, now let us implement it with types.
Fill<T, N, Start?, End?>
, as you can see,Fill
accepts four types of parameters, of which T
and N
are required parameters, and Start
and End
are optional parameters.
The requirements for these parameters are: T
must be a tuple
, N
can be any type of value, Start
and End
must be integers greater than or equal to 0.
type exp = Fill<[1, 2, 3], 0> // expected to be [0, 0, 0]
In order to simulate the real function, the test may contain some boundary conditions, I hope you can enjoy it :)
