Any variable.

variable

Any variable.

The increment and decrement operators are used as a shortcut to modify the value stored in a variable. The value of an expression containing one of these operators depends on whether the operator comes before or after the variable:

	Copy Code
var j, k; k = 2; j = ++k;

j is assigned the value 3, as the increment occurs before the expression is evaluated.

Contrast the following example:

	Copy Code
var j, k; k = 2; j = k++;

Here, j is assigned the value 2, as the increment occurs after the expression is evaluated.
