Basic JavaScript - Decrement a Number with JavaScript

Tell us what’s happening:

OK, so I know I got this and the previous exercise correct however I’m confused by something. mainly this line in the hint
a–; // Now, ‘a’ is 4
–a; // Now, ‘a’ is 3
when I changed the variable to both of the challenges (Increments ++i; and decrement --i:) the answer was correct. However, per the hint on this challenge “a–;” and “–a;” gave different values, so shouldn’t the placements of the “–” or “++” with the variable give different values, thus the placement be wrong? the increment test said " myVar should equal 88. I’m not sure if that makes sense, please let me know if I can clarify
Thanks
Johnny

Your code so far

let myVar = 11;

// Only change code below this line
--myVar

Using the double minus signs before and after the variable are both valid syntax.

On line one, the variable a is declared and assigned the value 5.
On line two a is decremented using valid syntax so its value is now 4.
On line three a is decremented again using valid syntax so its value is now 3.

Happy coding

right, that rule for the “–i;” worked. For the “++i;” challenge it said that the myVar should = 88. I typed in both “++myVar;” and “myVar++;” and it said that both were correct. since they give different values, how is that question still correct?

Sorry that it’s not making sense. I appreciate your help
