Tips for keeping your cool when a listener is suggesting changing it to a const variable

How can I output the isChecked value to the parent component? This value indicates whether the checkbox is clicked or not. Unfortunately, changing it to const is not an option due to an assignment below. My linter is suggesting that I change it to const, but I need it to be mutable. Can anyone assist me in resolving this issue?

export class CheckboxConfigureComponent {

@Input() selectedProperty: DateRowConfigDto | LabelRowConfigDto | EnumRowConfigDto
@Output() filterEvent = new EventEmitter<boolean>()

constructor() {
}

updateFilter(): void {
    let isChecked: boolean;
    isChecked = this.selectedProperty.visible ?  true : false
    this.filterEvent.emit(isChecked)
}
}

'isChecked' is never reassigned. Use 'const' instead prefer-const ✖ 3 problems (3 errors, 0 warnings) 1 error and 0 warnings potentially fixable with the --fix option. husky > pre-commit hook failed (add --no-verify to bypass)

Answer №1

Consider making the value a constant since it is only modified in one place:

updateFilter(): void {
    const isChecked = this.selectedProperty.visible ? true : false;
    this.filterEvent.emit(isChecked);
}

You can simplify the assignment like this:

updateFilter(): void {
    const isChecked = this.selectedProperty.visible;
    this.filterEvent.emit(isChecked);
}

Alternatively, you can skip using isChecked altogether:

updateFilter(): void {
    this.filterEvent.emit(this.selectedProperty.visible);
}
