As soon as we've declared a variable, we can assign a value to it with the = sign, or assignment operator.

See that? As soon as we assign a different value to age, it points to that value and forgets the previous value.

Psst: only if we declare and assign a value to a variable is the process called initialization.

When we are assigning a value to a variable, the variable needs to be on the left side and the equals in the middle.
