What is the mainline opinion about Juche and Dengism in the actual Marxism-Leninism ideology ?

Hey, I want to precise that I'm not ML but I want to understand how it is nowadays. TBH I'm interested into politics but since I'm a bit young I don't have all the prerequiste to read all types theory ( I read only simple ones such as The Communist Manifesto), and I prefer to ask concerned people. So I'm wondering how Marxism-Leninism sees political ideas such as Dengism and Juche ?

(Sorry if there's some problems with how the question is asked, English isn't my native language)
