Escape the never-ending cycle of underscores with pesky lint problems

Here is the code that aims to exit the loop once the desired result is found by returning true

ngModel.$parsers.unshift(function (viewValue) {
                    let names = scope.vm.names;

                    _.find(names, function (elem) {
                        let name = elem.name;

                        if (name && viewValue) {
                            if (name.toLowerCase() === viewValue.toLowerCase()) {
                                ngModel.$setValidity('unique', false);
                                return true; // exit the loop
                            } else {
                                ngModel.$setValidity('unique', true);
                            }
                        }
                    });
                    return viewValue;
                });

The code is functioning correctly as expected, but lint detects an error saying:

 × Unnecessary 'else' after 'return'. (no-else-return)
 27 |                                     ngModel.$setValidity('unique', false);
 28 |                                     return true; // exit the loop
 29 |                                 } else {
    |                                        ^
 30 |                                     ngModel.$setValidity('unique', true);
 31 |                                 }
 32 |                             }

Is there a way to prevent this error from showing up or can we enhance the code for a more efficient solution?

Answer №1

If you want to address the lint warnings, consider implementing the following code snippet:

if (name && viewValue) {
    let isNameEqual = name.toLowerCase() === viewValue.toLowerCase();
    ngModel.$setValidity('unique', !isNameEqual);
    if (isNameEqual) {
        return true; // exit the loop
    }
}

In order to establish the status of unique, a boolean value is utilized. If this value evaluates to true, the function will return true.
