Advanced Assignment Operators
<![CDATA[
Advanced assignment operators combine the basic assignment and other operators into one functional operator.
OperatorExampleDescription
+=x+=yx = x + y;
-=x-=yx = x - y;
*=x*=yx = x * y;
/=x/=yx = x / y;
%=x%=yx = x % y;
xx = x
=x=yx = x y;
&=x&=yx = x & y;
|=x|=yx = x | y;
^=x^=yx = x ^ y;
All the advanced assignment operators, except for +=, will attempt to convert strings to numbers.
If strings are used with the += operator, the left operand is concatenated to the end of the right operand.
The following example uses the Addition Operator to Perform String Concatenation.
