 ### Animations
 
-TODO i can't remember how any of this works
+```sv
+animate:name
+```
+
+```sv
+animate:name={params}
+```
+
+```js
+animation = (node: HTMLElement, { from: DOMRect, to: DOMRect } , params: any) => {
+	delay?: number,
+	duration?: number,
+	easing?: (t: number) => number,
+	css?: (t: number, u: number) => string,
+	tick?: (t: number, u: number) => void
+}
+```
+
+```js
+DOMRect {
+	bottom: number,
+	height: number,
+	​​left: number,
+	right: number,
+	​top: number,
+	width: number,
+	x: number,
+	y:number
+}
+```
+
+---
+
+An animation is triggered when the contents of a [keyed each block](docs#Each_blocks) are re-ordered. Animations do not run when an element is removed, only when the each block's data is reordered. Animate directives must be on an element that is an *immediate* child of a keyed each block.
+
+Animations can be used with Svelte's [built-in animation functions](docs#svelte_animate) or [custom animation functions](docs#Custom_animation_functions).
+
+```html
+<!-- When `list` is reordered the animation will run-->
+{#each list as item, index (item)}
+	<li animate:flip>{item}</li>
+{/each}
+```
+
+#### Animation Parameters
+
+---
+
+As with actions and transitions, animations can have parameters.
+
+(The double `{{curlies}}` aren't a special syntax; this is an object literal inside an expression tag.)
+
+```html
+{#each list as item, index (item)}
+	<li animate:flip="{{ delay: 500 }}">{item}</li>
+{/each}
+```
+
+#### Custom animation functions
+
+---
+
+Animations can use custom functions that provide the `node`, an `animation` object and any `paramaters` as arguments. The `animation` parameter is an object containing `from` and `to` properties each containing a [DOMRect](https://developer.mozilla.org/en-US/docs/Web/API/DOMRect#Properties) describing the geometry of the element in its `start` and `end` positions. The `from` property is the DOMRect of the element in its starting position, the `to` property is the DOMRect of the element in its final position after the list has been reordered and the DOM updated.
+
+If the returned object has a `css` method, Svelte will create a CSS animation that plays on the element.
+
+The `t` argument passed to `css` is a value that goes from `0` and `1` after the `easing` function has been applied. The `u` argument is equal to `1 - t`.
+
+The function is called repeatedly *before* the animation begins, with different `t` and `u` arguments.
+
+
+```html
+<script>
+	import { cubicOut } from 'svelte/easing';
+
+	function whizz(node, { from, to }, params) {
+
+		const dx = from.left - to.left;
+		const dy = from.top - to.top;
+
+		const d = Math.sqrt(dx * dx + dy * dy);
+
+		return {
+			delay: 0,
+			duration: Math.sqrt(d) * 120,
+			easing: cubicOut,
+			css: (t, u) =>
+				`transform: translate(${u * dx}px, ${u * dy}px) rotate(${t*360}deg);`
+		};
+	}
+</script>
+
+{#each list as item, index (item)}
+	<div animate:whizz>{item}</div>
+{/each}
+```
+
+---
+
+
+A custom animation function can also return a `tick` function, which is called *during* the animation with the same `t` and `u` arguments.
+
+> If it's possible to use `css` instead of `tick`, do so — CSS animations can run off the main thread, preventing jank on slower devices.
+
+```html
+<script>
+	import { cubicOut } from 'svelte/easing';
+
+	function whizz(node, { from, to }, params) {
+
+		const dx = from.left - to.left;
+		const dy = from.top - to.top;
+
+		const d = Math.sqrt(dx * dx + dy * dy);
+
+		return {
+		delay: 0,
+		duration: Math.sqrt(d) * 120,
+		easing: cubicOut,
+		tick: (t, u) =>
+			Object.assign(node.style, {
+				color: t > 0.5 ? 'Pink' : 'Blue'
+			});
+	};
+	}
+</script>
+
+{#each list as item, index (item)}
+	<div animate:whizz>{item}</div>
+{/each}
+```

 ### `svelte/transition`
 
-TODO
+The `svelte/transition` module exports six functions: `fade`, `fly`, `slide`, `scale`, `draw` and `crossfade`. They are for use with svelte [`transitions`](docs#Transitions).
+
+#### `fade`
+
+```sv
+transition:fade={params}
+```
+```sv
+in:fade={params}
+```
+```sv
+out:fade={params}
+```
+
+---
+
+Animates the opacity of an element from 0 to the current opacity for `in` transitions and from the current opacity to 0 for `out` transitions.
+
+`fade` accepts the following parameters:
+
+* `delay` (`number`, default 0) — milliseconds before starting
+* `duration` (`number`, default 400) — milliseconds the transition lasts
+
+You can see the `fade` transition in action in the [transition tutorial](tutorial/transition).
+
+```html
+<script>
+	import { fade } from 'svelte/transition';
+</script>
+
+{#if condition}
+	<div transition:fade="{{delay: 250, duration: 300}}">
+		fades in and out
+	</div>
+{/if}
+```
+
+#### `fly`
+
+```sv
+transition:fly={params}
+```
+```sv
+in:fly={params}
+```
+```sv
+out:fly={params}
+```
+
+---
+
+Animates the x and y positions and the opacity of an element. `in` transitions animate from an element's current (default) values to the provided values, passed as parameters. `out` transitions animate from the provided values to an element's default values.
+
+`fly` accepts the following parameters:
+
+* `delay` (`number`, default 0) — milliseconds before starting
+* `duration` (`number`, default 400) — milliseconds the transition lasts
+* `easing` (`function`, default `cubicOut`) — an [easing function](docs#svelte_easing)
+* `x` (`number`, default 0) - the x offset to animate out to and in from
+* `y` (`number`, default 0) - the y offset to animate out to and in from
+* `opacity` (`number`, default 0) - the opacity value to animate out to and in from
+
+You can see the `fly` transition in action in the [transition tutorial](tutorial/adding-parameters-to-transitions).
+
+```html
+<script>
+	import { fly } from 'svelte/transition';
+	import { quintOut } from 'svelte/easing';
+</script>
+
+{#if condition}
+	<div transition:fly="{{delay: 250, duration: 300, x: 100, y: 500, opacity: 0.5, easing: quintOut}}">
+		flies in and out
+	</div>
+{/if}
+```
+
+#### `slide`
+
+```sv
+transition:slide={params}
+```
+```sv
+in:slide={params}
+```
+```sv
+out:slide={params}
+```
+
+---
+
+Slides an element in and out.
+
+`slide` accepts the following parameters:
+
+* `delay` (`number`, default 0) — milliseconds before starting
+* `duration` (`number`, default 400) — milliseconds the transition lasts
+* `easing` (`function`, default `cubicOut`) — an [easing function](docs#svelte_easing)
+
+```html
+<script>
+	import { fly } from 'svelte/transition';
+	import { quintOut } from 'svelte/easing';
+</script>
+
+{#if condition}
+	<div transition:fly="{{delay: 250, duration: 300, easing: quintOut }}">
+		flies in and out
+	</div>
+{/if}
+```
+
+#### `scale`
+
+```sv
+transition:scale={params}
+```
+```sv
+in:scale={params}
+```
+```sv
+out:scale={params}
+```
+
+---
+
+Animates the opacity and scale of an element. `in` transitions animate from an element's current (default) values to the provided values, passed as parameters. `out` transitions animate from the provided values to an element's default values.
+
+`scale` accepts the following parameters:
+
+* `delay` (`number`, default 0) — milliseconds before starting
+* `duration` (`number`, default 400) — milliseconds the transition lasts
+* `easing` (`function`, default `cubicOut`) — an [easing function](docs#svelte_easing)
+* `start` (`number`, default 0) - the scale value to animate out to and in from
+* `opacity` (`number`, default 0) - the opacity value to animate out to and in from
+
+```html
+<script>
+	import { scale } from 'svelte/transition';
+	import { quintOut } from 'svelte/easing';
+</script>
+
+{#if condition}
+	<div transition:scale="{{duration: 500, delay: 500, opacity: 0.5, start: 0.5, easing: quintOut}}">
+		scales in and out
+	</div>
+{/if}
+```
+
+#### `draw`
+
+```sv
+transition:draw={params}
+```
+```sv
+in:draw={params}
+```
+```sv
+out:draw={params}
+```
+
+---
+
+Animates the stroke of an SVG path, like a snake in a tube. `in` transitions being with the path invisible and draw the path to the screen over time. `out` transitions start in a visible state and gradually erases the path. `draw` only works with SVG Path elements.
+
+`scale` accepts the following parameters:
+
+* `delay` (`number`, default 0) — milliseconds before starting
+* `speed` (`number`, default undefined) - the speed of the animation, see below.
+* `duration` (`number` | `function`, default 800) — milliseconds the transition lasts
+* `easing` (`function`, default `cubicInOut`) — an [easing function](docs#svelte_easing)
+
+The `speed` parameter is a means of setting the duration of the transition relative to the path's length. It is modifier that is applied to the length of the path: `duration = length / speed`. A path that is 1000 pixels with a speed of 1 will have a duration of `1000ms`, setting the speed to `0.5` will halve that duration and setting it to `2` will double it.
+
+```html
+<script>
+	import { draw } from 'svelte/transition';
+	import { quintOut } from 'svelte/easing';
+</script>
+
+<svg viewBox="0 0 5 5" xmlns="http://www.w3.org/2000/svg">
+	{#if condition}
+		<path transition:draw="{{duration: 5000, delay: 500, easing: quintOut}}"
+					d="M2 1 h1 v1 h1 v1 h-1 v1 h-1 v-1 h-1 v-1 h1 z"
+					fill="none"
+					stroke="cornflowerblue"
+					stroke-width="0.1px"
+					stroke-linejoin="round"
+		/>
+	{/if}
+</svg>

+```

+{@debug var1, var2, ..., varN}
+```
+
+---
+
+The `{@debug ...}` tag offers an alternative to `console.log(...)`. It allows you to inspect the value of a specific variable, but additionally pauses code execution when you have devtools open.
+
+```html
+<script>
+	let user = {
+		firstname: 'Ada',
+		lastname: 'Lovelace'
+	};
+</script>
+
+{@debug user}
+
+<h1>Hello {user.firstname}!</h1>
+```
+
+---
+
+`{@debug ...}` can also accept a comma-separated list of values, however it accepts only variable identifiers, and as such does not support inspecting of expressions.
+
+```sv
+# Compiles
+{@debug user}
+{@debug user1, user2, user3}
+
+# WON'T compile
+{@debug user.firstname}
+{@debug myArray[0]}
+{@debug !isReady}
+{@debug typeof user === 'object'}
+```

 ## Using a local copy of Svelte
 
-By default, the REPL will fetch the most recent version of Svelte from https://unpkg.com/svelte. To use the local copy of the compiler and runtime from this repo, you can navigate to [localhost:3000/repl?version=local](http://localhost:3000/repl?version=local). To produce the proper browser-compatible UMD build, you will need to run `npm run build` with the `PUBLISH` environment variable set (to any non-empty string).

Subject: [PATCH 81/87] Fix CRUD example to allow changing input values.

Currently, the first name and last name inputs fields can't be edited without the changes immediately being overwritten back to the selected person's first name and last name. This change will make it so that the input fields only get overwritten with the selected person's first name and last name when the selected person is changed.
