myMap= [0:'Mohit',1:'Balesh',2:'Jatin'];
arr[];

Expected Result arr['Mohit','Balesh','Jatin']

Map.values() returns a MapIterator object which can be converted to Array using Array.from:

let values = Array.from( myMap.values() );
// ["a", "b"]

To get an array from the values in a map you can spread the map values into an array using the Javascript spread operator (...) with the values() method of map.

yourArray = [...myMap.values()]

// gives the array ['Mohit', 'Balesh', 'Jatin']

First of all, your myMap is not valid. It should look like this:

myMap= {0:'Mohit',1:'Balesh',2:'Jatin'};

And getting an array from it should look like this:

myArr = Object.values(myMap);
