Generic type variables
The `Range` object generic type variables

A generic type variable constrained by the number
, by default of the value captured from the supplied min
indicates the minimum range type of a new Range
instance.
class Range<
Min extends number, // <--- Declare generic type variable Min.
Max extends number,
Step extends number = 1

constructor(
min: Min, // <--- Capture generic type variable Min.
max: Max,
value?: number,
step: Step = 1 as Step
) { }
}

A generic type variable constrained by the number
, by default of the value captured from the supplied max
indicates the maximum range type of a new Range
instance.
class Range<
Min extends number,
Max extends number, // <--- Declare generic type variable Max.
Step extends number = 1

constructor(
min: Min,
max: Max, // <--- Capture generic type variable Max.

A generic type variable constrained by the number
, by default of the value equal to 1
, optionally captured from the supplied step
indicates the range step type of a new Range
instance.
class Range<
Min extends number,
Max extends number,
Step extends number = 1 // <--- Declare generic type variable Step.
> {
constructor(
min: Min,
max: Max,
value?: number,
step: Step = 1 as Step // <--- Capture generic type variable Step.
) { }
}
