Answer 1

let mp: Map<string, number> = new Map([["typescript", 5], ["javascript", 8], ["nodejs", 4], ["c++",9], ["c", 1]])

for (let i: number = 0; i < mp.size; i++) {
    let key: string = Array.from(mp.keys())[i];                
    let value: any = mp.get(key);       
    console.log(key + " : " + value);
}
