Specifies how a CSS animation should progress over the duration between each keyframe pair

1. linear: same speed from start to end
2. ease(default): slow start, speed up then slow end
3. ease-in: animation has a slow start
4. ease-out: animation has a slow end

4. ease-in-out: animation has both slow start and end

4. cubic-bezier(x,x,x,x): define your own speed curve of the animation

1. Introduced in Angular 2 release

2. Built on top of the standard Web Animations API
3. A whole new wave of animation features in 4.2

4. ng6 supports and fallbacks CSS automatically if not supported in native browsers - no polyfill required

5. Polyfill required only when AnimationBuilder is used

6. Reusable and full-router level animations
7. State observations and translations

1. AnimationBuilder is an injectable service

2. Experimental

3. Purpose of this service is to produce an animation sequence programmatically within an angular component or directive

4. Programmatic animations are first built and then a player is created when the build animation is attached to an element

1. void => * same as :enter

2.  * => void same as :leave

3. void <=> * same as capturing state change between two states

4. 0 => 1 same as false => true

5. 1 => 0 same as true => false

1. trigger(); defines a name to use in the template to trigger the animation

2. transition(); defines the states in which the animation should run

3. style(); defines styles for each state and the animation duration, delay and easing with animate()

4. animate(); defines an animation step that combines styling information with timing information

5. animation(); produces a reusable animation that can be invoked in another animation or sequence, by calling the useAnimation() function

6. query(); finds one or more inner elements within the current element that is being animated within a sequence

7. stagger(); use within an animation query() call to issue a timing gap after each queried item is animated

8. group(); defines a list of animation steps to be run in parallel

9. sequence(); defines a list of animation steps to be run sequentially, one by one

10. keyframes(); set of animation styles with optional offset data; the optional offset value for a style specifies a percentage of the total animation time at which that style is applied

11. animateChild(); executes a queried inner animation element within an animation sequence

12. useAnimation(); starts a reusable animation that is created using the animation() function

1. Programming with asynchronous data streams

2. Stream - sequence of ongoing events ordered in time

3. Events has hooks to be observed and react on

4. We constantly react to changes when building an application

1. HTML, CSS and SVG

2. RxJS

3. Angular AnimationBuilder Module

1. Look to avoid animating properties that will trigger layout repainting which is expensive

1.1. Animating properties is not free, and some properties are cheaper to animate than others: width and height of an element changes its geometry and may cause other elements on the page to move or change size. This process is called layout and can be expensive if your page has a lot of elements

2. To achieve silky smooth animations you need to avoid work, and the best way to do that is to only change properties that affect compositing -- transform and opacity

3. Deside carefully wich animations are best fit for you - imperative(jsavaScript) vs declarative(css)
