Can anyone tell me what's happening in the below code ?
c = 0b101010011
c # => 339
c[0] # => 1
c[1] # => 1
c[2] # => 0
c[3] # => 0
c[4] # => 1
here `c` is not an array,but how then c[0],c[1], etc producing output
and how those outputs are coming ?

can you explain the below code ?
12 === Fixnum # => false
Fixnum === 12 # => true
Why different result is getting printed?

After spending some time I figured it out:
Why `Fixnum === 12 # => true` ?
Fixnum.respond_to?(:===) # => true
Fixnum.method(:===).owner # => Module
As per the documentation of Module#===
Case Equality—Returns true if **anObject is an instance of mod** or one
of mod’s descendants. Of limited use for modules, but can be used in
case statements to classify objects by class.
Why `12 === Fixnum # => false` ?
Got answer from here -

I think it's a matter of order it comes in.
It is similar to saying
"string' === String # => false
String === "string" # => true.
