!= inequality operator

Tests for the exact opposite of the equality (
, the result is

depends on the data types being compared, as illustrated in the following list:
Numbers, strings, and Boolean values are compared by value.
Objects, arrays, and functions are compared by reference.
A variable is compared by value or by reference, depending on its type.
Comparison by value means what most people would expect equals to mean--that two
expressions have the same value. For example, the expression (2 + 3) is equal to the expression
(1 + 4) when compared by value.
Comparison by reference means that two expressions are equal only if they both refer to the
same object, array, or function. Values inside the object, array, or function are not compared.
When comparing by value, if

The following example illustrates the result of the inequality (
trace(5 != 8); // returns true
trace(5 != 5) //returns false
The following example illustrates the use of the inequality (
var a:String = "David";
var b:String = "Fool";
