intersection observer - I can't change Value of Variable using match media in Javascript

Question

I just defined a variable called "option" for my Intersection Observer Threshold but it's not changing when I'm using match media.

here's the code :

{
let option = {threshold:0.8};
let mediaQuery1 = window.matchMedia('(min-width:1250px)');
if(mediaQuery1.matches){
       option.threshold= 1;
}
