What's the more common practice for passing data to $.getJSON: using variables or hard coding inline?

I know the video says both are common, but I'd love to know which is more common // or considered best practice. Are there performance improvements either way?

Seems like the latter would be easier to debug as there is less obfuscation. Are there other considerations?

Thanks! JS

I don't think there's an easy answer for this, since getting the numbers to determine the more common approach would be difficult/near impossible, and 'best practice' is always a subjective opinion shared by a number of people.

As far as the use of variables go, I think the rule of thumb is that if you need it more than once or it makes it clearer to read and understand the code, then use a variable.
