# JavaScript: Increment and Decrement Operator

The increment operator `++` and decrement operator `--` are two other mathematical assignment operators.

The increment operator increases the variable’s value by one. The decrement operator decreases the variable’s value by one.

For example: Increment Operator

``````let x = 99;
x++;
console.log(x); // Output: 100``````

For example: Decrement Operator

``````let x = 99;
x--;
console.log(x); // Output: 98``````

The variable’s value is changed and assigned as the variable’s new value, just as the previous mathematical assignment operators `+=`, `-=`, `*=` and `/=`.
