Using return; to end a script

[Yen]

Lately, I've been getting lazy and using 'if (condition) return;' instead of piling up the if (condition) { if (condition) { if (condition) { } } }
Is there any harm that can be caused by doing this?

For example..

PHP Code:

function onActionDamage(dmg,from,fromguild) {
  if (player.guild == fromguild && player.guild.length() > 0) return;
  if (player.account == from) return;
  if (client.allies.index(from) >= 0) return;
  client.hp -= dmg;
} 


Instead of..

PHP Code:

function onActionDamage(dmg,from,fromguild) {
  if (player.guild != fromguild || player.guild.length <= 0) {
    if (player.account != from) {
      if (client.allies.index(from) == -1) {
        client.hp -= dmg;
      }
    }
  }
}

No harm at all, although, it doesn't end the script - it just stops the current function from being executed further.

return; can be used as the first line of a script to comment it out!
