+Renders a tag input field.
+
+- Define a `TagInput` component and use the `useState()` hook to initialize an array from `tags`.
+- Use `Array.prototype.map()` on the collected nodes to render the list of tags.
+- Define the `addTagData` method, which will be executed when pressing the `Enter` key.
+- The `addTagData` method calls `setTagData` to add the new tag using the spread (`...`) operator to prepend the existing tags and add the new tag at the end of the `tagData` array.
+- Define the `removeTagData` method, which will be executed on clicking the delete icon in the tag.
+- Use `Array.prototype.filter()` in the `removeTagData` method to remove the tag using its `index` to filter it out from the `tagData` array.
