#Rule Details

This rule requires identifier variables within the same declaration block to be sorted alphabetically. Destructuring declarations are ignored. By default, ordering is case-sensitive.

Examples of incorrect code for this rule:

let b, a;
let c, D, e;

Examples of correct code for this rule:

let a, b, c;
let G, f, h;
let { b, a } = value;

With { "ignoreCase": true }, names are compared without case sensitivity:

{ "sort-vars": ["error", { "ignoreCase": true }] }

let a, A;
let c, D, e;

The rule can automatically reorder declarations when every participating initializer is a literal. It reports without a fix when reordering might change evaluation order.
