-/**
- * A cross-field validator that evaluates whether two form controls do or do
- * not have the same input value (except for empty string values). This validator
- * gets added to the entire FormGroup, not to an individual FormControl, like so:
- *
- * > ```
- * > formGroup = new FormGroup({
- * >   password: new FormControl(),
- * >   confirmPassword: new FormControl(),
- * > },
- * > {
- * >   validators: compareInputs(...),
- * > });
- * > ```
- *
- * Notes:
- * - Validation is controlled from either form control.
- * - The error message is displayed under controlB by default, but can be set to controlA.
- * - For more info on custom validators and cross-field validation:
- *   - https://v18.angular.dev/guide/forms/form-validation#defining-custom-validators
- *   - https://v18.angular.dev/guide/forms/form-validation#cross-field-validation
- *
- * @param validationGoal Whether you want to verify that the form controls do or do not have matching input values.
- * @param controlNameA The name of the first form control to compare.
- * @param controlNameB The name of the second form control to compare.
- * @param errorMessage The error message to display if there is an error. This will probably
- *                     be an i18n translated string.
- * @param showErrorOn The control under which you want to display the error (default is controlB).
- *
- * @returns A validator function that can be used on a FormGroup.

-   *                  perform validation on the FormGroup, which is a subclass of AbstractControl.
-   *                  The reason we validate at the FormGroup level and not at the FormControl level
-   *                  is because we want to compare two child FormControls in a single validator, so
-   *                  we use the FormGroup as the common ancestor.
-   *
-   * @returns A ValidationErrors object if the validation fails, or null if the validation passes.
