calling a function vs coding directly

I have this code for textarea autoheight 

   function h(el) {
        $(el).height(el.scrollHeight);
    }

$('textarea').each(function () {
    h(this); //  works
    //$(this).height($(this).scrollHeight);  //  doesn't work
});

$('textarea').on('input', function () {
    h(this);  // works
    //$(this).height($(this).scrollHeight);  //  dosen't work
});

If I replace h(this) with commented lines - they doesn't work. What is the reason?

In your group that doesn't work, you are converting this to jQuery both on .height and .scrollHeight, but in your function h, you only convert the el to jQuery on height

$('textarea').each(function () {
    $(this).height(this.scrollHeight);
});
