The with statement adds an object to the scope of every statement nested within. This can shorten the code of some statement groups that rely on a particular object reference. Note that with constructions are generally very inefficient. You can achieve better performance by assigning the object reference to a local variable, and using that variable in your function.

Example

with (document.forms[0]) { name1 = firstName.value; name2 = lastName.value; mail = eMail.value; }
