I'm aware I can use $.extend to merge to objects. What if I want to merge/update an array into an existing array, which is teh value of one of the properties of an object?
Obj = {id: 63, region: "place", shops: Array[246]}
$.extend(true, Obj.traits, amendedShopsArray) // Doesnt work
to return Obj = {id: 63, region: "place", amendedShopsArray: Array[246]
You can add a second key to the object with the same data, and then delete the one you do not want:
// shops mocked for simplicity
var obj = {id: 63, region: 'place', shops: [1, 2, 3]};
obj.amendedShopsArray = obj.shops;
delete obj.shops;
console.log(obj);Since $.extend will not merge arrays, you can use Array.concat like this:
var newArray = [.....];
Obj.shops = Obj.shops.concat(newArray);
If you want to change the property name:
var newArray = [.....];
Obj.amendedShopsArray = Obj.shops.concat(newArray);
delete Obj.shops;
