executing a string as a command in JS or Jquery

Question

I am building a website using HTML. In the js file I have an array of various city names.

I want to store in sessionStorage the city name as a key and a number as a value (depending on an if statement). I know I can use for example:

sessionStorage.London= 1;

but what if I don't know the names before hand or I want to write one line in a loop in order to do that ?

To be clearer, What I want is to be able to do something like:

sessionStorage.cityName[i]= 1;

Any solution is welcome

If you have dynamic object properties, to which you want to assign values, you can do it like sessionStorage[ cityName[i] ] = 1;

I would use a JSON string in sessionStorage (If I understood your question right):

 // Get the session storage cities object:
 var cities = JSON.parse(sessionStorage.getItem('cities'));

// Set a new city
cities['london'] = 1;

// Save the updated item
 sessionStorage.setItem('cities', JSON.stringify(cities));
