Explain the difference between $message and $$message?

Answer
$message is used to store variable data. $$message can be used to store variable of a variable. Data stored in $message is fixed while data stored in $$message can be changed dynamically.

E.g. $var1 = ‘Variable 1’
$$var1= ‘variable2’
This can be interpreted as $ Variable 1=‘variable2’;

For me to print value of both variables, I will write
$var1 $($var1)
