symbols in ruby


Symbols are good way to save memory,What's that mean?. When object is created each time in ruby it is allocated with a memory,when we instantiate same object again and again it will also create a additional new memory.But symbols don't lets look in to a example

When ever we instantiated the same object in each time the object_id of that string object gives different memory locations but in case of symbols memory location are same.Thats means symbols can hold the same for each call but string cannot.
