}
</script>

<button on:click={handleClick}>Click me</button>

<input on:keydown={handleKeyPress} placeholder="Press any key" />

Example of Form Submission

Handling Form Submissions

<script>

}
</script>

<form on:submit={handleSubmit}>
  <input type="text" placeholder="Enter something" />
  <button type="submit">Submit</button>
</form>
