Adding a value to a map in typescript

I must be missing something here. I try to put a value into a map but it doesn't want to work.

const tempMap = new Map();
tempMap.set("bla", "bla");
console.log(tempMap)
--> output: {}

Can someone explain to me why it is like that? Shouldn't the output have the added value in it?

Try it yourself in the playground.

In the end I used the Record type for my purpose. Which is a kind of dictionary type.

The class itself won't export any values, use should use the API

You want to do something like this:

let tmpMap = new Map();
tmpMap.set("bla", "bla");
console.log(tmpMap.get('bla')); // bla

You can also iterate in tempMap.keys() or tempMap.values() like @Evan already commented.
