Hi-Yo! When you just started learning to program, you tend to discover new strange keywords along the way. Is it better to keep learning how to use every new keyword you found OR just leave it until you need it(probably)?
At 2021, we are now farther from the 1980's than they were from the 1950's. Consider that the next time you long for a 1980's song, when you thought your grandpa's taste for 1950's music was "outdated".
