statement The statement for which object is the default object. Can be a compound statement.
The with statement is commonly used to shorten the amount of code that you have to write in certain situations. For example:
x = Math.cos(3 * Math.PI) + Math.sin(Math.LN10) // Notice how often Math. is used. y = Math.tan(14 * Math.E)becomes:with (Math) { x = cos(3 * PI) + sin (LN10) // Much shorter, easier to read code. y = tan(14 * E) }
