If somebody here happens to have free time can you help me with a dilemma? Some time ago a guy told me that anybody who thinks he can become great at any coding language without reading books is being very naive. I was just wondering if this statement is true and if it's truly impossible to achieve this without books because in this modern age with so many more learning sources there are more options than just using books for gathering all the knowledge but at the same time, there is truth in the fact that well written book can sometimes teach you more about the topic than eg. tutorials. What's your opinion on this?
