Should I use alias or alias_method?

Question

I found a blog post on alias vs. alias_method. As shown in the example given in that blog post, I simply want to alias a method to another within t

Answer 1

alias_method new_method, old_method

old_method will be declared in a class or module which is being inherited now to our class where new_method will be used.

these can be variable or method both.

Suppose Class_1 has old_method, and Class_2 and Class_3 both of them inherit Class_1.

If, initialization of Class_2 and Class_3 is done in Class_1 then both can have different name in Class_2 and Class_3 and its usage.
