Function isArray

isArray<T = unknown>(
    value: unknown,
    is?:
        | ((value: unknown, index: number) => boolean)
        | readonly ((value: unknown, index: number) => boolean)[],
): value is T[]
Checks if a value is an array.

Supports two validation modes:
- Element predicate: validates all elements with a single predicate function
- Tuple template: validates each element against a corresponding predicate function
Type Parameters
- T = unknown
  The type of array elements
Parameters
- value: unknown
  The value to check
- Optionalis:
  | ((value: unknown, index: number) => boolean)
  | readonly ((value: unknown, index: number) => boolean)[]
  Optional element predicate or tuple template:
  
  As function: validates all elements; receives the element value and its index
  
  As array: validates as tuple; each element must match the corresponding predicate
Returns value is T[]
True if the value is an array matching the validation criteria; false otherwise

Tuple templates require exact length match.
