6,387 PointsToo much "We can" and not enough "Why we do this" in this video
Well this is not a question per se, its more feedback related. Until this video i was completly able to follow all of his steps, but in the middle of the CRUD-topic the author is jumping into a boat full of "we can's". It would be more helpful to explain why we - for example - write the following statement:
if( $options != '' ) {
$wptreehouse_username = $options['wptreehouse_username'];
}

if options (an array) is not empty, assign this variable ($wptreehouse_username) to one of the options's values.
Why? Well, it looks like an example code snippet that is taken out of context. I can't tell you the exact reason why, but one reason for passing an array key's value is that it is shorter and simpler. It also allows the options array can be changed or modified. Maybe we want to be able to say last username's name. We wouldn't be able to, if we kept the only instance of that data inside of the options array.
