function printMap(value : any, key : any) {
    console.log(`Key: ${key}, Value: ${value}`);
}
 
const mp = new Map([
  ['str', 'typescript'],
  ['arr', [434, 627, 189, 910]],
]);
 
console.log([...mp.entries()]);
 
mp.forEach(printMap);   
   
console.log(mp.get('arr'));  
 
console.log(mp.get('arr')[0]);  
console.log(mp.get('arr')[1]);  
console.log(mp.get('arr')[2]);  
console.log(mp.get('arr')[3]);  
 
console.log(mp.get('arr').length);  
 
for (let i = 0; i < mp.get('arr').length; i++)
      console.log(mp.get('arr')[i]);
