Pls can anyone explain it

Question

MyNum = 42

# Trying to change the value produces a warning
MyNum = 8

Answer 1

Interesting. I saw the first(Most popular) comment on that lesson and that guy is completely right.
Its value can be modified (it produces a warning not error!).
But it's a very common (recommended) pattern to begin "constant" variable names with a capital letter. For that reason it produces a warning.
I don't know much Ruby just making assumptions.

Answer 8

If you start the name of the variable with a capital letter, Ruby will understand it is a constant therefore it can't change value once defined.
Problem would be solved if you started the name of the variable with a miniscule like below:
___________________________
myNum = 42
# puts myNum - this outputs 42
# Trying to change the value produces a warning
myNum = 8
# puts myNum - this outputs 8 - confirms the value of the variable has been changed
