map Iterate in TypeScript

In TypeScript, we can iterate over a hash (also known as an object) using a loop. Here's an example:

const myObj = {
	name: "John",
	age: 30,
	country: "USA"
};
for (let key in myObj) {

	console.log(key + ": " + myObj[key]);

}

In this example, we have defined an object called myObj with three key-value pairs. To iterate over the object using a loop, we use the for..in loop syntax.

Inside the loop, we use the key variable to access each key in the object, and use the [key] syntax to get the value associated with each key. We then log each key-value pair to the console.

This will output:

name: John
age: 30
country: USA

Note that the order of the keys cannot be guaranteed in an object/hash, so they may be output in a different order each time the loop is run.
