// A simple way to extract strings and numbers from an enum

enum actions {
 Link = 1,
 Unlink = 0
}

const strings =  Object.keys(actions)
 .filter((key) => Number.isNaN(parseFloat(key)))

const numbers = Object.keys(actions)
 .filter((key) => !Number.isNaN(parseFloat(key)))
 .map(x => parseInt(x, 10))

console.log('strings', strings) // [ 'Link', 'Unlink' ]
console.log('numbers', numbers) // [ 0, 1 ]
