As we saw in the former section, the catch() operator does a good job of ensuring that a stream that errors out doesn't cause any problems when being merged with another stream. The catch() operator enables us to take the error, investigate it, and create a new Observable that will emit a value as though nothing happened. Sometimes, however, you don't want to even deal with streams that error out. For such a scenario, there is a different operator, called onErrorResumeNext():
// error-handling/error-ignore.jsconst Rx = require("rxjs/Rx");let mergedIgnore$ = Rx.Observable.onErrorResumeNext( Rx.Observable.of(1), Rx.Observable.throw("err"), Rx.Observable.of(2));mergedIgnore$.subscribe(data => console.log("merge ignore", ...
