Than to decode this javascript?

The question is, I read here and on the forums - the specific answer do not give. Once the final answer. I would like to know for the future how to decoding these things.

The script is obfuscated.

Can use any service for deobfuscation, such jsbeautifier.org (there are many similar). But all the source code is not restored, do not expect.
And you said JS cannot defend? - elliott.Cartwrig commented on June 10th 19 at 16:36
well the first part I decrypted HEX + decode64
_0x258679,_0x10f2f9 - this part I do not understand. - vernon.Nicolas commented on June 10th 19 at 16:39
this guy has videos on this theme: https://www.youtube.com/watch?v=qzGLCqW_wrM

In General, search online deobfuscator, I like this code was dismantled. - Gerda57 commented on June 10th 19 at 16:42

_0x258679,_0x10f2f9 - this part I do not understand.
so in fact of the matter is that for PC as well as all the variables are called, and you do not understand. Obfuscators and minifactory can do
(do) irreversible changes to the original text it is impossible to recover, and we can only guess about what was in the original. - Austen.Thompson53 commented on June 10th 19 at 16:45
the algorithm here it is in front of you. Name variables and functions changed, but the logic can be understood. - Austen.Thompson53 commented on June 10th 19 at 16:48

Than to decode this javascript?
It's impossible.
What has not been encrypted will not be able to decipher.

Well, you have obfuscated code miner. If you look closely, you will see a simple operation. If you trace, you will see how this all translates into understandable operations and challenges. Access to functions is via a window, for example window["Math"]["cos"](1). From that moment you had to sign and all questions had to fall for granted. If not then alas, programming isn't for you, at the moment.

Is _0x5d8e.map(e => e.toString()) is not a solution?
