thor && thor.weapon && thor.weapon.stormbreaker
into:
object2.get('weapon.stormbreaker', thor)
Put-allows you to refactor this:
if(!thor.info ) {
thor.info={}
}
if(!thor.info.name){
thor.info.name={}
}
thor.info.name.actorname = "Chris Hemsworth"
into:
object2.put("thor.info.name.actorname",avengers,"Chris Hemsworth")
Delete-allows you to refactor this:
if(thor && thor.weapon && thor.weapon.stormbreaker){
delete thor.weapon.stormbreaker
}
into:
object2.delete('weapon.stormbreaker', thor)
