/// ### What it does

///

/// This rule enforces a minimum and/or maximum identifier length convention by counting the

/// graphemes for a given identifier.

///

/// ### Why is this bad?

///

/// Very short identifier names like e, x, _t or very long ones like

/// hashGeneratorResultOutputContainerObject can make code harder to read and potentially less

/// maintainable. To prevent this, one may enforce a minimum and/or maximum identifier length.

///

/// ### Examples

///

/// Examples of **incorrect** code for this rule:

/// ```js

/// /*eslint id-length: "error"*/ // default is minimum 2-chars ({ "min": 2 })

///

/// const x = 5;

/// obj.e = document.body;

/// const foo = function (e) { };

/// try {

/// dangerousStuff();

/// } catch (e) {

/// // ignore as many do

/// }

/// const myObj = { a: 1 };

/// (a) => { a * a };

/// class y { }

/// class Foo { x() {} }

/// class Bar { #x() {} }

/// class Baz { x = 1 }

/// class Qux { #x = 1 }

/// function bar(...x) { }

/// function baz([x]) { }

/// const [z] = arr;

/// const { prop: [i]} = {};

/// function qux({x}) { }

/// const { j } = {};

/// const { prop: a} = {};

/// ({ prop: obj.x } = {});

/// ```

///

/// Examples of **correct** code for this rule:

/// ```js

/// /*eslint id-length: "error"*/ // default is minimum 2-chars ({ "min": 2 })

///

/// const num = 5;

/// function _f() { return 42; }

/// function _func() { return 42; }

/// obj.el = document.body;

/// const foo = function (evt) { /* do stuff */ };

/// try {

/// dangerousStuff();

/// } catch (error) {

/// // ignore as many do

/// }

/// const myObj = { apple: 1 };

/// (num) => { num * num };

/// function bar(num = 0) { }

/// class MyClass { }

/// class Foo { method() {} }

/// class Bar { #method() {} }

/// class Baz { field = 1 }

/// class Qux { #field = 1 }

/// function baz(...args) { }

/// function qux([longName]) { }

/// const { prop } = {};

/// const { prop: [name] } = {};

/// const [longName] = arr;

/// function foobar({ prop }) { }

/// function foobaz({ a: prop }) { }

/// const { a: property } = {};

/// ({ prop: obj.longName } = {});

/// const data = { "x": 1 }; // excused because of quotes

/// data["y"] = 3; // excused because of calculated property access
