Around 10 years ago, Jeff Atwood (the founder of stackoverflow) made a case that JavaScript is going to be the future and he coined the “Atwood Law” which states that *Any application that can be written in JavaScript will eventually be written in JavaScript*. Fast-forward to today, 10 years later, if you look at it it rings truer than ever. JavaScript is continuing to gain more and more adoption.

### JavaScript is announced ### JavaScript is announced
JavaScript was initially created by [Brendan Eich](https://twitter.com/BrendanEich) of NetScape and was first announced in a press release by Netscape in 1995. It has a bizarre history of naming; initally it was named `Mocha` by the creator, which was later renamed to `LiveScript`. In 1996, about a year later after the release, NetScape decided to rename it to be `JavaScript` with hopes of capitalizing on the Java community (although JavaScript did not have any relationship with Java) and released Netscape 2.0 with the official support of JavaScript.

In 1996, Netscape decided to submit it to [ECMA International](https://en.wikipedia.org/wiki/Ecma_International) with the hopes of getting it standardized. First edition of the standard specification was released in 1997 and the language was standardized. After the initial release, `ECMAScript` was continued to be worked upon and in no-time two more versions were released ECMAScript 2 in 1998 and ECMAScript 3 in 1999.

The features of `SPDY` included, multiplexing, compression, prioritization, security etc. I am not going to get into the details of SPDY, as you will get the idea when we get into the nitty gritty of `HTTP/2` in the next section as I said `HTTP/2` is mostly inspired from SPDY.

# What is HTTP? # What is HTTP?
HTTP is the `TCP/IP` based application layer communication protocol which standardizes how the client and server communicate with each other. HTTP follows a classical "Client-Server model" with a client opening a connection request, then waiting until it recieves a response. HTTP is a stateless protocol, that means that the server does not keep any data (state) between two requests.

# Observable lifecycle # Observable lifecycle
An observable is a function that acts as a wrapper for a data stream. They support to pass messages inside your application. An observable is useless until an observer subscribes to it. An observer is an object which consumes the data emitted by the observable. An observer keeps receiving data values from the observable until the observable is completed, or the observer unsubscribes from the observable. Otherwise observers can receive data values from the observable continuously and asynchronously. So we can perform various operations such as updating the user interface, or passing the JSON response.
There are 4 stages for a life cycle of an observable.
- Creation
- Subscription
- Execution
- Destruction

# Operators # RxJS Operators
RxJS is mostly useful for its operators, even though the Observable is the foundation. Operators are the essential pieces that allow complex asynchronous code to be easily composed in a declarative manner.
Operators are functions. There are two kinds of operators:
**Pipeable Operators** are the kind that can be piped to Observables using the syntax observableInstance.pipe(operator()). These include, filter(...), and mergeMap(...). When called, they do not change the existing Observable instance. Instead, they return a new Observable, whose subscription logic is based on the first Observable.
A Pipeable Operator is essentially a pure function which takes one Observable as input and generates another Observable as output. Subscribing to the output Observable will also subscribe to the input Observable.
**Creation Operators** are the other kind of operator, which can be called as standalone functions to create a new Observable. For example: of(1, 2, 3) creates an observable that will emit 1, 2, and 3, one right after another. Creation operators will be discussed in more detail in a later section.
## Piping
Pipeable operators are functions, so they could be used like ordinary functions: op()(obs) — but in practice, there tend to be many of them convolved together, and quickly become unreadable: op4()(op3()(op2()(op1()(obs)))). For that reason, Observables have a method called .pipe() that accomplishes the same thing while being much easier to read:
```bash
obs.pipe(op1(), op2(), op3(), op4());
```
## Creation Operators
**What are creation operators?** Distinct from pipeable operators, creation operators are functions that can be used to create an Observable with some common predefined behavior or by joining other Observables.
A typical example of a creation operator would be the interval function. It takes a number (not an Observable) as input argument, and produces an Observable as output:
```bash
import { interval } from 'rxjs';
const observable = interval(1000 /* number of milliseconds */);
```
<BadgeLink colorScheme='blue' badgeText='Official Website' href='https://rxjs.dev/guide/operators#creation-operators-list'>List of creation operators</BadgeLink>
## Higher-order Observables
Observables most commonly emit ordinary values like strings and numbers, but surprisingly often, it is necessary to handle Observables of Observables, so-called higher-order Observables.

To enter the dev tools, right click and click **Inspect** (or press `ctrl+shift+c`/`cmd+opt+c`) to enter the Elements panel. Here you can debug CSS and HTML issues. If you want to see logged messages or interact with javascript, enter the **Console** tab from the tabs above (or press `ctrl+shift+j`/`cmd+opt+j` to enter it directly). Another very useful feature in the Chrome dev tools is the Lighthouse (for checking perfomance) — more on this later.
NOTE: This isn't a chrome-specific feature, and most browsers (Chromium based or otherwise) will have their own, largely-similar set of devtools.
