Try looking into existing JS functions that convert characters expressed in specific formats (e.g. 2-digit hexadecimal numbers like \x32) to other formats. Also look at the format each set of hex numbers in the obfuscated set is in. The last set is in a different format to the rest. You may need to do some format switching on the sets of hex numbers so that the JS conversion function that you think may work can parse it. This can be done by copying and pasting the set of numbers into a text editor, then search and replace on the appropriate characters within the pasted string to get the desired format for whatever conversion function you think will work.
