need help getting rid of javascript commands in ckeditor

Question

I am currently working on a small project to create a simple social media web app and i am using Laravel. I used CK editor to make the posts in my media , but i found out that,I can use Javascript commands from the editor by going to the source code section. How can i make it so that the commands don't run but also at the same time have a option to have bold, italic and different fonts and headers.

The following is my code for posting the posts or text;

*<div class="flex justify-center">
<div class="w-9/12 p-3 bg-stale-700 " > 
@if ($posts->count())
    @foreach ($posts as $post)
        <div class="mb-4 p-4 bg-gray-300 rounded " >
        <a href="" class="font-bold" > {{$post->user->username}} </a> 
        <span class=" p-3 text-sm"> {{$post->created_at->toTimeString()}} </span>
        {!!$post->body!!}
        </div>
    
     @endforeach
        {{ $posts->links('pagination::tailwind') }} 
@else
There are no posts        
@endif
<div>*

The following is the code for ckeditor:

 *<form action="{{route('post')}}" method="post" >
         @csrf
         <textarea name="post"></textarea>
                <script>
                        CKEDITOR.replace( 'post' );
                </script>
                @error('post')
                    <p class=" small-text red-200 "> This feild is required </p>
                @enderror
                <br>
                <button class="bg-transparent hover:bg-blue-500 text-blue-700 font-semibold hover:text-white py-2 px-4 border border-blue-500 hover:border-transparent rounded"> post </button> 
        </form>*

If possible, I am looking for editor like stackoverflow has, Thank you
