Display textarea value in Laravel

I have posts. When I click edit it takes me to the edit screen and display current post values. However for some reason the input is displayed while textarea is not. I can't understand why.

Works perfectly, displays value.

<input class = "form-control" type="text" name = 'body' value = "{{ old('body', $post->body ?? null) }}" />

It doesn't display value for body.

<textarea class="form-control" type="text" name = 'body'  rows="3" value = "{{ old('body', $post->body ?? null) }}" ></textarea>

input is self closing tag that's why in input you can set value via value=
and in textarea there is closing tag that's why in textarea you can't set value via value attribute

<textarea class="form-control" type="text" name = 'body'  rows="3"> {{ old('body', $post->body) }}</textarea>

The textarea tag has no value, but work fine with handlebars.it has placeholder attribute but here it not work like this https://html.spec.whatwg.org/multipage/forms.html#attr-textarea-placeholder
So just give the value before close tag

<textarea class="form-control" type="text" name = 'body'  rows="3" >{{ old('body', $post->body ?? null) }}</textarea>
