-Notes about Implementation
---------------------------
-
-### Observables are cold
-
-The underlying JSONRPC method is only called if there's at least one subscriber.
-
-```javascript
-import { balanceOf$ } from '@parity/light.js';
-
-const myObs$ = balanceOf$('0x123');
-// Observable created, but `eth_getBalance` not called yet
-const subscription = myObs$.subscribe(console.log);
-// `eth_getBalance` called for the 1st time
-
-// Some other code...
-
-subscription.unsubscribe();
-// `eth_getBalance` stops being called
-```
-
-### Observables are PublishReplay(1)
-
-Let's take `blockNumber()$` which fires blocks 7, 8 and 9, and has 3 subscribers that don't subscribe at the same time.
-
-We have the following marble diagram (`^` denotes when the subscriber subscribes).
-
-```
-blockNumber$(): -----7----------8------9-----|
-subscriber1:    -^---7----------8------9-----|
-subscriber2:    ------------^7--8------9-----|
-subscriber3:    --------------------------^9-|
-```
-
-Note: the default behavior for Observables is without PublishReplay, i.e.
-
-```
-blockNumber$(): -----7----------8------9-----|
-subscriber1:    -^---7----------8------9-----|
-subscriber2:    ------------^---8------9-----|
-subscriber3:    --------------------------^--|
-```
-
-But Observables in this library are PublishReplay(1). [Read more](https://blog.angularindepth.com/rxjs-how-to-use-refcount-73a0c6619a4e) about PublishReplay.
-
-### Observables are memoized
-
-```javascript
-const obs1$ = balanceOf$('0x123');
-const obs2$ = balanceOf$('0x123');
-console.log(obs1$ === obs2$); // true
-
-const obs3$ = balanceOf$('0x456');
-console.log(obs1$ === obs3$); // false
-```
-
-### Underlying API calls are not unnessarily repeated
-
-```javascript
-const obs1$ = balanceOf$('0x123');
-const obs2$ = balanceOf$('0x123');
-
-obs1$.subscribe(console.log);
-obs1$.subscribe(console.log);
-obs2$.subscribe(console.log);
-// Logs 3 times the balance
-// But only one call to `eth_getBalance` has been made
-
-const obs3$ = balanceOf$('0x456');
-// Logs a new balance, another call to `eth_getBalance` is made
-```
-
-### Underlying PubSub subscriptions are dropped when there's no subscriber
-
-```javascript
-import { blockNumber$ } from '@parity/light.js';
-
-const myObs$ = blockNumber$();
-console.log(blockNumber$.frequency); // [onEveryBlock$]
-// Note: onEveryBlock$ creates a pubsub on `eth_blockNumber`
-
-const subscription = myObs$.subscribe(console.log);
-// Creates a pubsub subscription
-
-// Some other code...
-
-subscription.unsubscribe();
-// Drops the pubsub subscription
-```
