What are unicode-property-aliases-ecmascript's main functionalities?
Mapping Unicode Property Aliases
This feature allows you to map a Unicode property alias to its canonical property name. For example, the alias 'scx' maps to 'Script_Extensions'.
const unicodePropertyAliases = require('unicode-property-aliases-ecmascript');
console.log(unicodePropertyAliases.get('scx')); // Outputs: 'Script_Extensions'
Iterating Over All Aliases
This feature allows you to iterate over all the alias-canonical name pairs in the mapping. This can be useful for debugging or for generating documentation.
const unicodePropertyAliases = require('unicode-property-aliases-ecmascript');
for (const [alias, canonical] of unicodePropertyAliases) {
console.log(`${alias} -> ${canonical}`);
