Lab 2. Create a countdown timer using fromEvent, map, and scan

Debug your observable streams with tap

Introduction to filtering operators

Emit a set number of values from a stream with take

Complete a stream when a condition is met with takeWhile

Complete a stream based on another stream using takeUntil

Ignore non unique values using distinctUntilChanged

Introduction to rate limiting operators

Take the latest value after a pause debounceTime

Ignore values during windows using throttleTime

Sample a stream on a uniform duration using sampleTime

Audit a stream for a duration after an event occurs using auditTime

Introduction to transformation operators

What’s a flattening operator?

Watch lesson

Flatten inner observables as they occur with mergeMap

Switch to a new observable on emissions using switchMap

Subscribe to observables in order with concatMap

Ignore emissions when an inner observable is active with exhaustMap

Catch errors on observables with catchError

Lab 3. Create an HTTP polling solution

Introduction to combination operators

Append values to a stream using startWith and endWith

Queue observable execution using concat

Watch lesson

Combine multiple active observables using merge

Receive the latest values from multiple observables on emissions using combineLatest

Receive the latest value from multiple observable on completion with forkJoin
