-
-This command is used for intensive profiling of ESLint using Chrome Developer Tools. It starts a development server that runs through three profiles:
-
-* Large - Runs ESLint on JSHint
-* Medium - Runs ESLint on jQuery
-* Small - Runs ESLint on KnockoutJS
-
-Your browser should automatically open to the page in question. When that happens:
-
-1. Open up developer tools
-1. Click on Profiles
-
-You should start to see profiles for each run show up on the left side. If not, reload the page in the browser. Once all three profiles have completed, they will be available for inspection.

* `getSourceCode()` - returns a [`SourceCode`](#context-getsourcecode) object that you can use to work with the source that was passed to ESLint.
* `markVariableAsUsed(name)` - marks a variable with the given name in the current scope as used. This affects the [no-unused-vars](../rules/no-unused-vars.md) rule. Returns `true` if a variable with the given name was found and marked as used, otherwise `false`.

**Note:** Earlier versions of ESLint supported additional methods on the `context` object. Those methods were removed in the new format and should not be relied upon.
### Options Schemas
-Rules may export a `schema` property, which is a [JSON schema](http://json-schema.org/) format description of a rule's options which will be used by ESLint to validate configuration options and prevent invalid or unexpected inputs before they are passed to the rule in `context.options`.
+Rules may export a `schema` property, which is a [JSON schema](https://json-schema.org/) format description of a rule's options which will be used by ESLint to validate configuration options and prevent invalid or unexpected inputs before they are passed to the rule in `context.options`.
There are two formats for a rule's exported `schema`. The first is a full JSON Schema object describing all possible options the rule accepts, including the rule's error level as the first argument and any optional arguments thereafter.
In the preceding example, the error level is assumed to be the first argument. It is followed by the first optional argument, a string which may be either `"always"` or `"never"`. The final optional argument is an object, which may have a Boolean property named `exceptRange`.
-To learn more about JSON Schema, we recommend looking at some examples in [website](http://json-schema.org/learn/) to start, and also reading [Understanding JSON Schema](http://spacetelescope.github.io/understanding-json-schema/) (a free ebook).

**Note:** Currently you need to use full JSON Schema object rather than array in case your schema has references ($ref), because in case of array format ESLint transforms this array into a single schema without updating references that makes them incorrect (they are ignored).

-## Environments
+Please note that this rule validates regular expressions per the latest ECMAScript specification, regardless of your parser settings.
-ECMAScript 6 adds the following flag arguments to the `RegExp` constructor:
-
-* `"u"` ([unicode](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-get-regexp.prototype.unicode))
-* `"y"` ([sticky](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-get-regexp.prototype.sticky))
-
-You can enable these to be recognized as valid by setting the ECMAScript version to 6 in your [ESLint configuration](../user-guide/configuring).
-
-If you want to allow additional constructor flags for any reason, you can specify them using an `allowConstructorFlags` option in `.eslintrc`. These flags will then be ignored by the rule regardless of the `ecmaVersion` setting.

+# Disallow `\8` and `\9` escape sequences in string literals (no-nonoctal-decimal-escape)
+
+Although not being specified in the language until ECMAScript 2021, `\8` and `\9` escape sequences in string literals were allowed in most JavaScript engines, and treated as "useless" escapes:
+
+```js
+"\8" === "8"; // true
+"\9" === "9"; // true
+```
+
+Since ECMAScript 2021, these escape sequences are specified as [non-octal decimal escape sequences](https://tc39.es/ecma262/#prod-annexB-NonOctalDecimalEscapeSequence), retaining the same behavior.
+
+Nevertheless, the ECMAScript specification treats `\8` and `\9` in string literals as a legacy feature. This syntax is optional if the ECMAScript host is not a web browser. Browsers still have to support it, but only in non-strict mode.
+
+Regardless of your targeted environment, these escape sequences shouldn't be used when writing new code.
+
+## Rule Details
+
+This rule disallows `\8` and `\9` escape sequences in string literals.
+
+Examples of **incorrect** code for this rule:
+
+```js
+/*eslint no-nonoctal-decimal-escape: "error"*/
+
+"\8";
+
+"\9";
+
+var foo = "w\8less";
+
+var bar = "December 1\9";
+
+var baz = "Don't use \8 and \9 escapes.";
+
+var quux = "\0\8";
+```
+
+Examples of **correct** code for this rule:
+
+```js
+/*eslint no-nonoctal-decimal-escape: "error"*/
+
+"8";
+
+"9";
+
+var foo = "w8less";
+
+var bar = "December 19";
+
+var baz = "Don't use \\8 and \\9 escapes.";
+
+var quux = "\0\u0038";

+# disallow use of optional chaining in contexts where the `undefined` value is not allowed (no-unsafe-optional-chaining)
+
+The optional chaining (`?.`) expression can short-circuit with a return value of `undefined`. Therefore, treating an evaluated optional chaining expression as a function, object, number, etc., can cause TypeError or unexpected results. For example:
+
+```js
+var obj = undefined;
+
+1 in obj?.foo; // TypeError
+with (obj?.foo); // TypeError
+for (bar of obj?.foo); // TypeError
+bar instanceof obj?.foo; // TypeError
+const { bar } = obj?.foo; // TypeError
+```
+
+Also, parentheses limit the scope of short-circuiting in chains. For example:
+
+```js
+var obj = undefined;
+
+(obj?.foo)(); // TypeError
+(obj?.foo).bar; // TypeError
+```
+
+## Rule Details
+
+This rule aims to detect some cases where the use of optional chaining doesn't prevent runtime errors. In particular, it flags optional chaining expressions in positions where short-circuiting to `undefined` causes throwing a TypeError afterward.
+
+Examples of **incorrect** code for this rule:
+
+```js
+/*eslint no-unsafe-optional-chaining: "error"*/
+
+(obj?.foo)();
+
+(obj?.foo).bar;
+
+(foo?.()).bar;
+
+(foo?.()).bar();
+
+(obj?.foo ?? obj?.bar)();
+
+(foo || obj?.foo)();
+
+(obj?.foo && foo)();
+
+(foo ? obj?.foo : bar)();
+
+(foo, obj?.bar).baz;
+
+(obj?.foo)`template`;
+
+new (obj?.foo)();
+
+[...obj?.foo];
+
+bar(...obj?.foo);
+
+1 in obj?.foo;
+
+bar instanceof obj?.foo;
+
+for (bar of obj?.foo);
+
+const { bar } = obj?.foo;
+
+[{ bar } = obj?.foo] = [];
+
+with (obj?.foo);
+
+class A extends obj?.foo {}
+
+var a = class A extends obj?.foo {};
+
+async function foo () {
+ const { bar } = await obj?.foo;
+ (await obj?.foo)();
+ (await obj?.foo).bar;
+}
+```
+
+Examples of **correct** code for this rule:
+
+```js
+/*eslint no-unsafe-optional-chaining: "error"*/
+
+(obj?.foo)?.();
+
+obj?.foo();
+
+(obj?.foo ?? bar)();
+
+obj?.foo.bar;
+
+foo?.()?.bar;
+
+(obj?.foo ?? bar)`template`;
+
+new (obj?.foo ?? bar)();
+
+var baz = {...obj?.foo};
+
+const { bar } = obj?.foo || baz;
+
+async function foo () {
+ const { bar } = await obj?.foo || baz;
+ (await obj?.foo)?.();
+ (await obj?.foo)?.bar;
+}
+```
+
+## Options
+
+This rule has an object option:
+
+- `disallowArithmeticOperators`: Disallow arithmetic operations on optional chaining expressions (Default `false`). If this is `true`, this rule warns arithmetic operations on optional chaining expressions, which possibly result in `NaN`.
+
+### disallowArithmeticOperators
+
+With this option set to `true` the rule is enforced for:
+
+- Unary operators: `-`, `+`
+- Arithmetic operators: `+`, `-`, `/`, `*`, `%`, `**`
+- Assignment operators: `+=`, `-=`, `/=`, `*=`, `%=`, `**=`
+
+Examples of additional **incorrect** code for this rule with the `{ "disallowArithmeticOperators": true }` option:
+
+```js
+/*eslint no-unsafe-optional-chaining: ["error", { "disallowArithmeticOperators": true }]*/
+

- 3. Use the same single mechanism to support "private" and "user" data.
- 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
- 5. Avoid exposing implementation details on user objects (eg. expando properties)
