how can succeed in js?

yes, result different, because javascript function doesn't base64 encoding @ all.

the base64 encoded data contains 6 bits of information per character, 8 bits of character code spread out on 2 characters in encoded data.

to encode data, have regroup bits in bytes 6 bit groups, can convert each group base64 character.
