The way I think about it is, whenever you have X: Y where X and Y are
identifiers, the one on the left is fixed and the one on the right is variable.
- In an object literal, the one on the left is a symbolic property name and the
one on the right is a variable.
- In destructuring, the one on the left is the fixed name of the property
you're destructuring and the one on the right is the variable name you're
locally binding.
- In module importing, the one on the left is the fixed name of the foreign
export you're importing, and the one on the right is the variable name you're
locally binding.
