multiple conditions in an if statement in javascript

Question

I know there has been a question like this, but mine is a little different, and it already works, but I don't know how to simplify it.

if (location.pathname === `/` || location.pathname ===`/kurikulum/` || location.pathname === `/pengembangan-diri/` || location.pathname === `/statistik/` || location.pathname === `/teknologi/` || location.pathname === `/ekonomi/` || location.pathname === `/desain/` || location.pathname === `/corona/`)

as you can see it is not beautiful, I wonder can we make it without repeating location.pathname?

this is on gatsby, but it is a javascript question

You can use Array.includes to check if the current pathname exists in a given array.

let pathArr = ['/', '/kurikulum/', '/pengembangan-diri/', '/statistik/', '/teknologi/', '/ekonomi/', '/desain/', '/corona/'];
let testPath = '/desain/';

if (pathArr.includes(testPath)) {
   document.write('path found!');
};
