`Rx.Observable.prototype.sequenceEqual(second, [comparer])`

Determins whether two sequences are equal by comparing the elements pairwise using a specified equality comparer.

Arguments

second (Observable | Promise | Array): Second observable sequence, Promise or array to compare.
[comparer] (Function): Comparer used to compare elements of both sequences.

Returns

(Observable): An observable sequence that contains a single element which indicates whether both sequences are of equal length and their corresponding elements are equal according to the specified equality comparer.

Example

var source1 = Rx.Observable.return(42);
var source2 = Rx.Observable.return(42);

var source = source1.sequenceEqual(source2);

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });

// => Next: true
// => Completed
