Sed special parsing

What is the shortest & right way to remove the string "[]" with a sed statement ?

Code:
echo 'whatever[]whatever' | sed ........

Something like this?
Code:
sed 's/\[]//'

Now another question :

When entering the following command

Code:
# echo 'whatever[]whatever' | sed 's/[[]]//'
whateverwhatever

if we consider :
Code:
[ [ ] ]
1 2 3 4

1) Which pair of bracket will be interpreted first ?

a) 14 ?
b) 13 ?
c) 24 ?
d) 23 ?

2) Could you find or build an example that demonstrate this ?

Smilie
