Yes, you could translate this as "I'll enjoy it", but a closer translation would be "I'll make the most of it", as in "I'm not going to pass up the chance of enjoying this". The basic phrase is 'profiter de quelque chose', which means to take advantage of something (such as an opportunity), usually in a positive sense. A good way of looking at the pronoun 'en' is the 'de' from the basic phrase combined with the object: 'of it', if you like. So, if the weather's nice, you might say "Je vais profiter du beau temps" to mean "I'm going to make the most of the nice weather". Or, if you don't need to repeat the reference to the weather, you could say "I'm going to make the most of it" by saying "Je vais en profiter", with 'en' meaning 'of it'. I hope that helps.

alors, "en" is like the thing ur about to enjoy, for example if ur going on a holiday "en" is a replacement for the word "a holiday" i think... i hope this helps

"Je vais en profiter"= le en fait référence la chose dont tu vas profiter. "Je veux en manger" le en désigne la chose dont il est question

Yes, "en" here means "it". So it can be translated by "I will enjoy it".
