coalescing

The coalescing() function takes a value or an array and normalizes it into an array. If the value is not already an array, it is wrapped in an array.

Interactive example

Syntax

function coalescing<
	GenericInput extends AnyValue
>(
	input: GenericInput
): ArrayCoalescing<GenericInput>

ArrayCoalescing returns an array if the input is not one, or keeps the input array. This guarantees the result is always an array.

Parameters

• input: A value or an array of values.

Return value

An array. If input is already an array, it is returned as is. Otherwise, the value is wrapped in an array.
