Operator repeat() is somewhat similar to retry(), but is not for handling operators. In this lesson we learn how repeat works.
var foo = Rx.Observable.interval(500)
.zip(Rx.Observable.of('a','b','c','d'), (x,y)=>y); var bar = foo.map(x => x.toUpperCase()); /*
--a--b--c--d| (foo)
map(toUpperCase)
--A--B--C--D| (bar)
repeat
--A--B--C--D--A--B--C--D--A--B--C--D|
*/ var result = bar.repeat(3); result.subscribe(
function (x) { console.log('next ' + x); },
function (err) { console.log('error ' + err); },
function () { console.log('done'); },
);
