[netrexx-course] *this* keyword

[Terry Norton-2]

I'm having a mental block understanding the *this* keyword.

Could someone explain to me why I would use *this*?  It just
seems redundant to me so I know I'm not getting the concept for
its use.

You might want to use it to make sure of which variable is getting set.

e.g. given the class:

class Test
   x = "Blah"
method junk(x, y)
   x= 12


Which x is being set?? (The method parameter unfortunately). So if you really want to set the class's property x, use:

   this.x = 12

Clearer??
