[A-Z]{2} RegEx matches only two cap letters, not sure how to proceed from here.

Answer 1

Assuming,you have

1)Name starting with capital Letter followed by some small letters -> [A-Z][a-z]*

2)Capital Middle Letter-> [A-Z]

3)Capital Last Letter followed by some small letters -> [A-Z][a-z]*

U can split them into 3 groups

(^[A-Z][a-z]*)([A-Z])([A-Z][a-z]*)

Since you need first and last group.You can get like this -> $1$3

Eg.

'JohnJSmith'.replace(/(^[A-Z][a-z]*)([A-Z])([A-Z][a-z]*)/,'$1$3')->"JohnSmith"
