# Counter Component Task
-Create a Svelte 5 component called Counter that implements a simple counter with increment and decrement functionality.
+Create a Svelte 5 component that implements a simple counter with increment and decrement functionality.
-## Requirements:
-
-1. Use Svelte 5's `$state` for reactivity
-2. The counter should start at 0
-3. Include a decrement button with the `data-testid="decrement-button"` attribute
-4. Include an increment button with the `data-testid="increment-button"` attribute
-5. Display the current count with the `data-testid="count-value"` attribute
-6. Clicking increment should increase the count by 1
-7. Clicking decrement should decrease the count by 1
-8. Style the counter with a CSS class "counter"
-
-Example structure:
-
-```html
-
-
- 0
-
-
-```
-
-Please implement this component using Svelte 5 syntax. Make sure you only return one component.
+Use Svelte 5's `$state` rune for reactivity. The component should have increment/decrement buttons and display the current count starting at 0.

-# $derived.by Component Task
+# Text Analyzer Component Task
Create a Svelte 5 component that demonstrates the `$derived.by` rune for complex derivations.
-## Requirements:
-
-1. Create a text input field that allows the user to enter text
-2. Use `$state` to store the current text value, starting with an empty string
-3. Use `$derived.by` to calculate:
- - The number of words in the text
- - The number of characters in the text
- - Whether the text is considered "long" (more than 15 words)
-4. Display all these derived values below the input field
-5. Include a "Clear" button that resets the text to an empty string
-
-Elements should have these data-testid attributes:
-
-- "text-input" for the input field
-- "word-count" for displaying the word count
-- "char-count" for displaying the character count
-- "length-indicator" for displaying whether the text is long
-- "clear-button" for the clear button
-
-Example structure:
-
-```html
-
-
-
-
-
Words: 0
-
Characters: 0
-
Status: Short text
-
-
-```

+Create a Svelte 5 component that demonstrates the basic use of snippets.
-## Requirements:
-
-1. Create a component with a hardcoded array of 3 book titles (strings) - "The Lord of the Rings", "To Kill a Mockingbird", and "1984"
-2. Create a snippet called `title` that takes a book title string as a parameter
-3. The snippet should display the book title in a `` element with `data-testid="book-title"`
-4. Use the `{@render ...}` syntax to render the snippet for each book title in a list
-5. Each rendered title should be wrapped in a `
