The basic building blocks of an Angular application are NgModules, which provide a compilation context for components.

Webpack has become the defacto standard when building Angular applications, you can check an introduction to Webpack post here on the Angular documentation.

System.js System was heavily used in the beginning whilst Angular was being built and during the release candidate stages before official release, however the team have switched to advocating Webpack instead due to it being much more powerful.

Angular CLI The Angular CLI was built to help scaffold new projects, create components and help with deployment. Underneath it utilises Webpack for you.

An Angular app is defined by a set of NgModules.

An app always has at least a root module that enables bootstrapping, and typically has many more feature modules.

Components define views, which are sets of screen elements.

Components use services, which provide specific functionality not directly related to views.

Service providers can be injected into components as dependencies, making your code modular, reusable, and efficient.

Both components and services are simply classes, with decorators that mark their type and provide metadata that tells Angular how to use them.

Metadata is a way of processing the class. A class will be a class unless we tell Angular that is a Component, Service etc. Decorators that mark their type and provide the metadata that tells Angular how to use them.

The metadata for a component class associates it with a template that defines a view.

The metadata for a service class provides the information Angular needs to make it available to components through dependency injection (DI).

Angular provides the Router service to help you define navigation paths among views.

An NgModule declares a compilation context for a set of components that is dedicated to an application domain, a workflow, or a closely related set of capabilities.

NgModules can import functionality from other NgModules, and allow their own functionality to be exported and used by other NgModules. For example, to use the router service in your app, you import the Router NgModule.

Organising your code into distinct functional modules helps in managing development of complex applications. This technique lets you take advantage of lazy-loading—that is, loading modules on demand—

Every Angular app has a root module, conventionally named AppModule, which provides the bootstrap mechanism that launches the application.

A template combines ordinary HTML with Angular directives and binding markup that allow Angular to modify the HTML before rendering it for display.

Most people understand life expectancy has changed since Social Security started in 1937 when folks lived to be 59 years old. Today, they live to be 77 years old.

The joy of the mind is the measure of its strength.

Ultimately, the American people ourselves need to decide we care more about practical solutions and progress than we do about brain-dead ideology and political wrangling.

I don't have any hidden talents but if you dare me to do something I'll go after it big time.

From the Bush Administration to the 9-11 Commission, there is an urgent and universally recognized need to change the broken formula through which Homeland Security grant money currently is allocated to our first responders.

My girlfriend has crabs, I bought her fishnet stockings.

Conservatives need to know how important it is to fill out the census. It is one of the only things our Constitution specifically asks of U.S. citizens and boycotting will just help liberals expand government even further.

A safe fairyland is untrue to all worlds.

As time passed on, got to hear some players who were straight up funky, not just jazz. Nat Adderley, for instance - he's a funky trumpet player, so he was my man.

Many Americans who have suffered during a recession have had to cut their spending 1 percent, and they didn't like doing it, but they were able to do it to get their family's finances back in order.

The worst part of success is, to me, adapting to it. It's scary.

The illegal we do immediately. The unconstitutional takes a little longer.

I'm really good at laundry, and I have no problem cleaning the kitchen.

Observations indicate that the universe is expanding at an ever increasing rate. It will expand forever, getting emptier and darker.

Grin and bear it.

As far as thinking about death and murder and various ways of killing people and how people die... I probably have the most twisted mind in Slayer.

I love designing, and I still do it.

The things we always disengage with are one-sided stories or one-sided characters. They're very boring. When you feel like you're being hit over the head, you disengage.

Tact in audacity is knowing how far you can go without going too far.

You act in a movie, and at the end of the day, the director and editor decide what your performance is.

I've been avoiding journalists my whole life.

I guess a psychiatrist would say there's some good to the venting process, but it does also promote an attitude of saying, 'Hey there's nothing wrong with being filled with hate; there's so much of it around.' I don't like that.

Rwanda has emerged from the devastation of genocide and become more secure and prosperous than anyone had a right to expect.

It's not very glamorous. People certainly wouldn't think so if they saw me sitting in my woolly socks at the kitchen table. Many times I sit at the typewriter and think, 'Why am I doing this?'
