The difference between pre- and post-increment is in the result of evaluating the expression itself.++i increments i and evaluates to the new value of i.i++ evaluates to the old value of i, and increments i. 0 answersPost by Maury Hillstrom on September 25, 2012Hi Leslie,At which point are you finding syntax errors? 0 answersPost by leslie stapleton leslie stapleton on September 12, 2012There seems to be syntax errors in this code!

### Operators

• Operators are familiar symbols (such as + - * / < >) that represent math functions, comparisons, boolean logic, and variable assignments
• JavaScript follows its own set of Arithmetic Rules of Precedence which is different from standard algebra
• Increment and Decrement operators are often used with Counters
