Angular Lifecycle methods should not be async. Angular does not wait for async lifecycle but the code incorrectly suggests it does. https://github.com/angular-eslint/angular-eslint/blob/main/packages/eslint-plugin/docs/rules/no-async-lifecycle-method.md
The @Attribute decorator is used to obtain a single value for an attribute. This is a much less common use-case than getting a stream of values (using @Input), so often the @Attribute decorator is mistakenly used when @Input was what was intended.

JSON schema for ESLint configuration files
By default, ESLint supports only ECMAScript 5 syntax. You can override that setting to enable support for ECMAScript 6 as well as JSX by using configuration settings.
Enables support for the experimental object rest/spread properties (IMPORTANT: This is an experimental feature that may change significantly in the future. It's recommended that you do not write rules relying on this functionality unless you are willing to incur maintenance cost when it changes.)
allow return statements in the global scope
enable global strict mode (if ecmaVersion is 5 or greater)
An environment defines global variables that are predefined.
AppleScript global variables
Ember test helper globals
GreaseMonkey globals
PhantomJS global variables
Prototype.js global variables
Protractor global variables
Service Worker global variables
WebExtensions globals
Prevent comments from changing config or rules

Set to 3, 5 (default), 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 to specify the version of ECMAScript syntax you want to use. You can also set it to 2015 (same as 6), 2016 (same as 7), 2017 (same as 8), 2018 (same as 9), 2019 (same as 10), 2020 (same as 11), 2021 (same as 12), 2022 (same as 13), 2023 (same as 14), or 2024 (same as 15) to use the year-based naming. You can also set "latest" to use the most recently supported version.
set to "script" (default), "commonjs", or "module" if your code is in ECMAScript modules
By default, ESLint will look for configuration files in all parent folders up to the root directory. This can be useful if you want all of your projects to follow a certain convention, but can sometimes lead to unexpected results. To limit ESLint to a specific project, set this to `true` in a configuration in the root of your project.
ESLint supports adding shared settings into configuration file. You can add settings object to ESLint configuration file and it will be supplied to every rule that will be executed. This may be useful if you are adding custom rules and want them to have access to the same information and be easily configurable.
Allows to override configuration for files and folders, specified by glob patterns
