They're both compressed to some degree although the second one has been both fully compressed and obfuscated while the first one seems to be extra-space and randomly new-line compressed.
This site here is a favorite of mine and does a good job on your first js file:

However, once a script file is obfuscated (variable and object names reduced), it's near-impossible to make sense of it unless you know specifically what's going on (or you have hours of spare time) and so your second JS file is a bit more difficult to decipher.
