combine

combine

Merges two objects, copying their properties onto a new combined object. When two objects have the same property, the value of the property on the first object is used. If either object is undefined, it will be treated as an empty object.

Parameters:
Name Type Argument Default Description
object1 Object <optional>
The first object to merge.
object2 Object <optional>
The second object to merge.
deep Boolean <optional>
false Perform a recursive merge.
Returns:
Object The combined object containing all properties from both objects.
Example
var object1 = {
    propOne : 1,
    propTwo : {
        value1 : 10
    }
}
var object2 = {
    propTwo : 2
}
var final = Cesium.combine(object1, object2);

// final === {
//     propOne : 1,
//     propTwo : {
//         value1 : 10
//     }
// }
