How to extract out the variable of special content format?

I have below data:

# == 2.This is a ==
111111
222222
# == 2.This is a ==

# == 3.This is b ==
333333
# == 3.This is b ==

4
5

# == 2.This is a ==
66
77
8
# == 2.This is a ==

# == 4.This is c ==
9

# == 5.This is d ==
11
12
13
# == 5.This is d ==

10
# == 4.This is c ==

you see the special format # == {variable} == I want to extract out the variables.

but I don't know how to do with this, I have searched SO, get:
Extract variable from special string format Python
Regex Python : extracting special content

but neither is suitable for this situation.

I'm not sure how to implement the solution in Javascript, but you can try something like this regex:

# == ([0-9.sa-zA-Z]+)
