// ============ example

const fct1 = (msg: string) => console.log(`fct 1 with msg=${msg}`)
const fct2 = (value: number) => console.log(`fct 2 with value=${value}`)
const fct3 = () => console.log(`fct 3`)
const fct4 = (o: any) => console.log(o)

Factory.bind(fct1)
Factory.bind(fct2)
Factory.bind(fct3)
Factory.bind(fct4)

// --------------- Using

Factory.call('fct1', 'Hello World')
Factory.call('fct2', 1000)
Factory.call('fct3')
Factory.call('fct4', {a: 1, b: 'coucou'})

console.log(Factory.exists('fct1'))
console.log(Factory.exists('fct5'))
console.log(Factory.names())
