Not an endorsement: I’m not sure how I feel about this yet, but reviewing code, I do tend to keep the constants at the end.
Today I learned that Yoda Conditions are a thing.
The core principal is to be consistent with where you put the constants in comparison operators.
Take the following examples:
if 42 == answer {}
if answer == 42 {}
By having the constant after the comparison, you can quickly scan the code for which variables are involved in the comparison.
