How to say ’Don't worry, I will‘ in Chinese?
My friend and I were messing about on Facebook today, we were talking in Chinese when I made a comment using English, My friend said "That's not Chinese" to which I replied "And?" He then said "好吧。。 隨便！" like do as you wish/will.
How would you say in reply 'Don't worry, I will!" in Chinese? I could only translate very literally 不要担心， 我会了 which does not strike me as right, even though we both got it lol.
Would the way you say it change depending on if you are messing about or saying it seriously? Here me and my friend were only joking but this could also be said in for example 'an argument'
