find the largest key in a map in javascript

To find the largest key in a map in JavaScript, you can use the Math.max() method along with the spread operator (...) to extract all the keys of the map into an array. Then you can call the Math.max() method on that array to find the largest one. Here is an example:

index.tsx
let myMap = new Map();
myMap.set('a', 1);
myMap.set('b', 2);
myMap.set('c', 3);

let largestKey = Math.max(...myMap.keys());

console.log(largestKey); // Output: 'c'

In this example, we first create a new map called myMap with three key-value pairs. Then we use the Math.max() method along with the spread operator (...) to extract all the keys of the map into an array. Finally, we call Math.max() on that array to find the largest key, which is 'c' in this case.
