formatting specified string in textarea field

[K.]

I have such a text

<input type="text" name="search_txt" value="">
<textarea name="txt_m">
My hobby is bicycle.
My hobby is driving a car.
</textarea>

I would like to bold and color a specified text
in input field search_txt for instance "hobby" string.

How to do that in JS?

Thank you in advance
Marcin

You can only apply the style properties that textarea elements support.
They can be applied to the textarea as a whole (e.g. font-family or
weight), the effect may work or not depending on browser support for
the particular property.

Full details (but not browser support) are in the W3C CSS spec, their
CSS property table provides hints:

A CSS group may provide more information

Could you be so kind and write me a small code example?

Thank you in advance
