const trimSize = 20;
let text = '<p>Something that is too big and you want to trim, and then renddeer in your HTML page.</p>';

let content = text.substring(3, text.length - 4);

let trimmedText = '<p>' + content.substring(0, trimSize) + '<\p>';

if ($request->hasFile('image')) {
   $image = $request->file('image');
   $filename = time() . '.' . $image->getClientOriginalExtension();
   $location = public_path('images/comment/' . $filename);
   Image::make($image)->resize(800, 600)->save($location);
}
