Find the largest number in an array
Check if given number is a prime number
Factorial of a given number

Thank you very much happy sir and All the best guys!

[sudheerdarla]

Thanks. Even more optimization for checking prime number is a for loop from 2 to SquareRoot(Givennumber).

[whatisimprov]

for largest number would this work
const findLargestNumber = (arr) => {
const largest = arr.sort().reverse();
return largest[0];
};
