API

This module exports a single function named matchPropertyValue.

`matchPropertyValue(property, value)`

This function takes a string property that is a canonical/unaliased Unicode property name, and a string value. It attemps to match value to a canonical Unicode property value for the given property. If there’s a match, it returns the canonical property value. Otherwise, it throws an exception.

// Find the canonical property value:
matchPropertyValue('Script_Extensions', 'Aghb')
// → 'Caucasian_Albanian'

matchPropertyValue('Script_Extensions', 'Caucasian_Albanian')
// → 'Caucasian_Albanian'

matchPropertyValue('script_extensions', 'Caucasian_Albanian') // Note: incorrect casing.
// → throws

matchPropertyValue('Script_Extensions', 'caucasian_albanian') // Note: incorrect casing.
// → throws
