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)?
I always told my DA fans how much I hate slot machines. They're fine in games as a risk-and-reward system. But when you're spending REAL MONEY in a Vegas casino to try and hit the jackpot (which very, very few people will), it can really hurt your budget. Gambling is a bad habit, and I don't like wasting my money on a slim chance. Go to Vegas for the experience, not the jackpot.
