dear sir: map itterators (for-in for-of getting error) for reading values getting problem ,
I am able to read values using for loop only.

Error as follows:
D:\TSPROJ>tsc mapdemo.ts
mapdemo.ts:1:19 - error TS2583: Cannot find name 'Map'. Do you need to change your target library? Try changing the lib compiler option to es2015 or later.

1 let proddata= new Map();

My code : mapdemo.js is as follows please suggest on this:

let proddata= new Map();
proddata.set(1,"samsung tv");
proddata.set(2,"Mobile");
proddata.set(3,"Canon cemara");
proddata.set(4,"pendirive");
console.log(prod data size ${proddata.size});
let otherprod=new Map([
[5,"datacard"],[6,"Data Reader"],[7,"Memory Card 32 GB"],[8,"64 gb memory card"]
]);

console.log(Other prod data size: ${otherprod.size});

let mycart:Map<number,string>=new Map([...Array.from(proddata.entries()),...Array.from(otherprod.entries())]);

console.log(card items size ${mycart.size});
console.log('ACCESSING VALUES INDIVIDUALLY')
console.log(mycart.get(1));
console.log(mycart.get(2));
console.log(mycart.get(3));
console.log(mycart.get(4));
console.log(mycart.get(5));
console.log(mycart.get(6));
console.log(mycart.get(7));
console.log(mycart.get(8));

console.log("1)ACCESSING VALUES USING ITERATOR-- entries")

for(var entry of mycart.entries())
{
console.log(entry[0]+"--"+entry[1]);

}

console.log("2)ACCESSING VALUES USING ITERATOR values ")

for(let val of mycart.values())
{
console.log(val);
}
console.log("3)ACCESSING VALUES USING ITERATOR keys")

for (let key of mycart.keys())
{

console.log(key.toString());

//console.log(mycart.values[key]);
console.log(mycart.get(key));

}

console.log(mycart.size);
console.log("4)ACCESSING VALUES USING for loop IT IS ONLY WORKING ")

for(var i=1;i<=mycart.size,i++;)
{
console.log(value is: +${mycart.get(i-1)});
if(i>mycart.size)
{break; }

}

//console.log("val1 is:" +mycart.get(1)+"Property:"+mycart.get(2));
