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'); },);
