| Explain why line 4 and line 6 output different numbers. | ||
| Because line 4 will print Local variable (which x is defined again) which is 2 but line 6 will print global variable which is 1 |

| line 32 print 10 and undefined because line 28 print 10 and y will return as undefined ,line 33 dosen't print anything because y is not defined globally. |

Line 32 will print undefined not because of y variable but because f1 function doesn't return anything. Line 33 will print a Reference Error because as you wrote, y not is defined globally

| 9 and {x:10} because in line 50 it console.log (x) which is 9 and in line 60 it console.log(y) which is {x:9} |

Correct, and this is because f1 and f2 functions don't modify x and y variables in the global scope

Remember to delete console logs (line 12 and 22) before committing

Well done! All works fine🙂 I would encourage you to always try to write a clean code - break the logic down into smaller functions and call them where needed.
| if (amount > 0) { | ||
| this.balance += amount; | ||
| } else { | ||
| console.log(`Please enter a positive number`); |
| console.log(`You have ${this.balance} in your account`); | ||
| } | ||
| make_withdrawl(amount) { | ||
| if (this.balance > amount && amount > 0) { |

Good error handling again - it shows that you think about what could go wrong

i could be something more meaningful here

How would you make sure that the song won't be repeated when shuffle is called multiple times in a row?
| this.i++; | ||
| this.play(); | ||
| } else { | ||
| console.log(`There isn't any song to play`); |

I think it's fine to console log that there are no more songs to play, but another solution could be to start playing songs from the beginning
