=Equality var a = 5, b = 10;
b = a;		 b = 5
+=Shorthand Addition var a = 5, b = 10;
b += a;		 b = 15
-=Shorthand Subtraction var a = 5, b = 10;
b -= a;		 b = 5
*=Shorthand Multiplication var a = 5, b = 10;
b *= a;		 b = 50
/=Shorthand Division var a = 5, b = 10;
b /= a;		 b = 2
&=Shorthand Bitwise AND var a = 5, b = 10;
b &= a;		 b = 0
|=Shorthand Bitwise OR var a = 5, b = 10;
b |= a;		 b = 15
^=Shorthand Bitwise XOR var a = 5, b = 10;
b ^= a;		 b = 15
<<=Shorthand Left Shift var a = 111111, b = 1010;
b <<= a;		 b = 129280
>>=Shorthand Sign-Propagating Right Shift var a = 111111, b = 1010;
b >>= a;		 b = 7
>>>=Shorthand Zero-Fill Right Shift var a = 111111, b = 1010;
b >>>= a;		 b = 7
