When a value is assigned to the property name (this.name = name;) JavaScript needs to set that property. When this happens, the setter function is triggered. In this example when the setter is triggered, it is told to do the same thing again: _to set the same property that it is meant to handle._ This causes the function to call itself, again and again, making it infinitely recursive. This issue also appears if the same variable is used in the getter. To avoid this problem, make sure that the property being assigned to inside the setter function is different from the one that initially triggered the setter. The same goes for the getter.
