    JavaScript solution:

    function Person(initialAge){
    if (initialAge < 0) {
        console.log("Age is not valid, setting age to 0.");
        this.age = 0;
    } else {
        this.age = initialAge;
    }
    
  this.amIOld=function(){
   if (this.age < 13) {
    console.log("You are young.");
   } else if (this.age >= 13 && this.age < 18) {
    console.log("You are a teenager."); 
   } else {
    console.log("You are old.");
   };
   
  };
   this.yearPasses=function(){
          this.age += 1;
   };
}
