Checks / Exit Conditions

Instead of writing something like if !condition throw … we may use require and check for quick exit conditions:

val num = 1;

require(num > 1){
    // ...
}

val num = 1;

require(num > 1){
    // ..
}

Adding pluralization as extension function

fun String.pluralize(count:Int):String {
    return if (count > 1){
        this + 's'
    } else {
        this
    }
}

Use it like this
