Angular NameOf in Component for String Safe and NgOnchanges

What is the best way to compare NgOnChanges, while making it String Type safe in Angular? Currently this is what I am doing.

NgOnChanges SimpleChanges variable is datatype : any and accepts any variable name, even if misspelled. Trying to find clean way to prevent this.

Original:

else if (changes?.product?.previousValue != changes?.product?.currentValue) {
    this.submitSearch();

New:

export const nameof = <T>(name: keyof T) => name;

public readonly productMember = nameof<WebStoreSearchComponent>("product");

if ((changes[this.productMember]?.previousValue == null || changes[this.productMember]?.previousValue?.length === 0) {
    this.submitSearch();

Does Angular have any native way to conduct this?
