sort-variable-declarations
Enforce sorted variable declarations within a scope.
Variable declarations within a block of code can quickly become disorganized and difficult to navigate, especially in larger functions or modules. With this rule, you can ensure that all variable declarations are consistently sorted, making it easier to locate specific variables and maintain a clean and structured codebase.
This practice improves readability and maintainability by providing a predictable order for variable declarations. It helps developers quickly understand the scope and usage of variables without having to search through an unsorted list.

order
default:'asc'Determines whether the sorted items should be in ascending or descending order.
'asc'— Sort items in ascending order (A to Z, 1 to 9).'desc'— Sort items in descending order (Z to A, 9 to 1).
