These are the tests is has to go through to pass:
const { maskPassword } = require('./solutions');
describe('Problem 2 - maskPassword() function', function() {
test('all characters should be masked by default', function() {
let password = 'sUp3rS3kR_t!';
let result = maskPassword(password);
expect(result).toBe('************');
});
test('all characters should be masked if charsToMask is 0', function() {

let result = maskPassword(password, 0);
expect(result).toBe('************');
});
test('first 3 characters should be unmasked if requested', function() {
let password = 'sUp3rS3kR_t!';
let result = maskPassword(password, 3);
expect(result).toBe('sUp*********');
