I had this pretty simple method:
// Loop over the themes
const activeIdWasFound = false;
const elementRef = this.elementRef.nativeElement.querySelector(`[id="${activeValue[0]}"]`);
if (elementRef !== null) {
activeIdWasFound = true;
}
You used it in if - else statement but after that it's not used again. That's why PHPStorm shows notice. Replace const
with let
// Loop over the themes
let activeIdWasFound = false;
const elementRef = this.elementRef.nativeElement.querySelector(`[id="${activeValue[0]}"]`);
if (elementRef !== null) {
activeIdWasFound = true;
}
