how to run a js file in my browser
<p>The first thanks to all, thanks to your answers I am learning to program little by little.</p>

<p>In the intranet of my office daily I have to make a query via browser that returns me about 1000 results. I have to check them all since I do not have a filtering option. Imagine that I have to look for the stock of red pens. Well the query only returns me all the pencils there are, without filtering color, size, etc.</p>

<p>I've written a script in javascript that filters the results and shows them by colors, sizes, etc, but to run it I have to press F12 to open the browser console and copy and paste the javascript code.</p>

<p>Is there any option for you to run the filtering directly from a js file without having to be pressing F12 and copying and pasting the code?</p>
