Kotlin Companion Object (under a minute)

A companion object is a powerful ally that lives inside a class, like a superhero living inside their secret lair. It’s like a sidekick who knows all the secrets and special abilities of the class, and can use them to help you fight crime and save the day.

For example, let’s say you have a class called SuperSuit, which represents a special suit that gives you superpowers. You might make a companion object to help you activate and deactivate the suit. You could write it like this:

class SuperSuit {
    companion object {
        fun activate() {
            // code to activate the suit
        }
        
        fun deactivate() {
            // code to deactivate the suit
        }
    }
}

Now you can use the activate and deactivate functions from the companion object to turn your powers on and off, like this:

SuperSuit.activate()
SuperSuit.deactivate()

So a companion object is like a trusty sidekick, always there to help you harness the full power of your class and become a superhero!
