Let's say a storage variable Product holds the following data:

{"partNumber": 1000, "name": "Smartphone"}

The following code will update the name field:

Apperyio.storage.Product.update("$['name']", "Smart Watch");
var p = Apperyio.storage.Product.get();
console.log(p);

{name: "Smart Watch", partNumber: 1000}

Here is another example but this time using a variable:

var fieldName = "name";
Apperyio.storage.Product.update("$['"+fieldName+"']", "Smart Watch");
var p = Apperyio.storage.Product.get();
console.log(p);

{name: "Smart Watch", partNumber: 1000}
