The following code could use a bit of object-oriented artistry. While it's a simple method and works just fine as it is, in a larger system it's best to organize methods into classes/objects. (Or, at least, something similar depending on your language)

Refactor the following code so that it belongs to a Person class/object. Each Person instance will have a greet method. The Person instance should be instantiated with a name so that it no longer has to be passed into each greet method call.

Here is how the final refactored code would be used:

var joe = new Person('Joe');
joe.greet('Kate'); // should return 'Hello Kate, my name is Joe'
joe.name           // should == 'Joe'

joe = new Person('Joe')
joe.greet('Kate') # should return 'Hello Kate, my name is Joe'
joe.name          # should == 'Joe'

joe = Person.new('Joe')
joe.greet('Kate') # should return 'Hello Kate, my name is Joe'
joe.name          # should == 'Joe'

let joe = Person::new("Joe");
joe.greet("Kate"); // should return "Hello Kate, my name is Joe"
joe.name;          // should == "Joe"

joe = Person('Joe')
joe.greet('Kate') # should return 'Hello Kate, my name is Joe'
joe.name          # should == 'Joe'

val joe = Person("Joe")
joe.greet("Kate") // should return "Hello Kate, my name is Joe"
joe.name          // should == "Joe"
