combine observables code example

Example 1: rxswift combine two observables

Observable.combineLatest(
            sourceObservableA, sourceObservableB,
            resultSelector: { value1, value2 in
                print("\(value1) \(value2)")
        }).observeOn(MainScheduler.instance)
            .subscribe()
            .disposed(by: disposeBag)

Example 2: javascript combine objects

const obj1 = {'a': 1, 'b': 2};
const obj2 = {'c': 3};
const obj3 = {'d': 4};

const objCombined = {...obj1, ...obj2, ...obj3};
