    I was having too much problem to understand JavaScript . I read docs , searched throughout UA-cam . I thought I won't ever understand JavaScript . Then I prayed to God and God made come to this channel. You explained everything such easily my brother I couldn't understand even after watching 60 videos from another JavaScript course
