MessageNumber.selectKey() method

In addition to matching exact values, numerical values will also match keys with the same plural rule category, i.e. one of zero, one, two, few, many, and other.

Signature:

selectKey(keys: Set<string>): string | null;

Parameters

Parameter	Type	Description
keys	Set<string>

Returns:

string | null

Remarks

Different languages use different subset of plural rule categories. For example, cardinal English plurals only use one and other, so a key zero will never be matched for that locale.
