Description

An empty destructuring pattern doesn’t provide any value and might be confusing, as it looks similar to the default assignment.

Non-Compliant Code Examples

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

Compliant Code Examples

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