Aim of the puzzle: Use the ++
and --
operators to change the value of a variable.
Walk through of solution: On the first line, the x
variable is defined with the value 5. The next line increments (adds 1 to) the x
variable. You can see the results printed by the next line.
Now, tap on the x
on the next line all by itself. Tap the --
button to decrement (subtract 1 from) the x
variable. When you run the code now you will see that the value of x
went back down by 1.
Sample code solution:
(Tap below to reveal)
let x = 5;
x++;
print('x is ' + x);
x--;
print('x is now ' + x);
