Desafío: Asigna el valor de una variable a otra variable

Enlaza al desafío:

A variable is like a container.
If container A is worthy £100 and I give you another empty container B and your task is to assign the value of container A to container B.

So here you just use an assignment operator = to equal a to b because both variables had already been declared for you and a has got a value already which you must assign to b so that they are of equal value.
