noEmptyPattern (since v0.7.0)

This rule is recommended by Rome.

Disallows empty destructuring patterns.

Examples

var {} = foo;

error[js/noEmptyPattern]: Unexpected empty object pattern.
  ┌─ js/noEmptyPattern.js:1:5
  │
1 │ var {} = foo;
  │     ^^

var {a: {}} = foo;

error[js/noEmptyPattern]: Unexpected empty object pattern.
  ┌─ js/noEmptyPattern.js:1:9
  │
1 │ var {a: {}} = foo;
  │         ^^

function foo({}) {}

error[js/noEmptyPattern]: Unexpected empty object pattern.
  ┌─ js/noEmptyPattern.js:1:14
  │
1 │ function foo({}) {}
  │              ^^

The following cases are valid because they create new bindings.

var {a = {}} = foo;
var {a, b = {}} = foo;
var {a = []} = foo;
function foo({a = {}}) {}
function foo({a = []}) {}
var [a] = foo;
