//With Object.fromEntries, you can convert from Map to Object:
const testMap = new Map([ ['hello', 'world'], ['lorem', 42] ]);
const result1 = Object.fromEntries(testMap);
console.log(result1); // { hello: "world", lorem: 42 }

//With Object.fromEntries, you can convert from Array to Object:
const testArray = [ ['first', 0], ['second', 1], ['third', 2] ];
const result2 = Object.fromEntries(testArray);
console.log(result2); // { first: 0, second: 1, third: 2 }

const testArray1 = ["It's Always Sunny in", "", "Philadelphia"];

// First using a map for comparison
testArray1.map(x => x.split(" "));
//returns [["It's", "Always", "Sunny","in"],[""],["Philadelphia"]]

// Now let us see flatMap in action!
testArray1.flatMap(x => x.split(" "));
//returns ["It's","Sunny","in", "", "Philadelphia"]

// The simple one :P 
const testArray1 = [1, 2, [3, 4]];
testArray1.flat(); // returns  [1, 2, 3, 4]

const testArray2 = [1, 2, [3, 4, [5, 6]]];
testArray2.flat();
// returns [1, 2, 3, 4, [5, 6]];
testArray2.flat(2); // goes two levels deep recursively as we passed the parameter
// returns [1, 2, 3, 4, 5, 6];
