// ... 
.onClick(() => { 
  let hashmap : HashMap<string,number> = new HashMap() 
  hashmap.set("Abc",123) 
  hashmap.set("Bcd",234) 
  hashmap.set("Cde",345) 
  for (let key of hashmap.keys()) { 
    testNapi.mapDemo(key, hashmap.get(key)) 
    console.info(`key is ${key}, value is ${hashmap.get(key)}`) 
  } 
}) 
// ...
