I'm trying to create a function that enters a key/value into a JSON file.

But, since value can be an `int` or `char`, I don't want to create 2 functions for each type.

Is there a way ?




    void setValue(char *key, char* value){
            StaticJsonDocument<512> tempJDOC;
            tempJDOC[key]=value;
    }

    myJSON(char *filename, bool useserial=false);
    
    bool file_exists();
    bool file_remove();
    bool format ();

    void readJSON_file(JsonDocument& _doc);
    
    void printJSON(JsonDocument& _doc);
    void PrettyprintJSON(JsonDocument& _doc);
    
    const char *getValue (char *key);
    
    template <class T>
    void setValue(const char *key, T value);
    //void setValue(const char *key, char *value);
    
    };
    #endif
