Change an array loaded from another component in React.js jsx - node.js

Question

I am trying to change a hardcoded array within another JSX file.
the first file routes.js. I tried loading the array then changing it . it just changes the loaded data not the array directly from the other file. How do i write to the other JSX array from the main component.
const routes = [
{
type: "collapse",
name: "Our Mission",
key: "dashboards",
icon: <Shop size="12px" />,
collapse: [
{
name: "Ways We can Help",
key: "default",
route: "/dashboards/default",
component: Default,
},
{
name: "How It Works",
key: "automotive",
route: "/dashboards/automotive",
component: Automotive,
},
{
name: "Who We Are",
key: "smart-home",
route: "/dashboards/smart-home",
component: SmartHome,
},
],
},
{ type: "title", title: " ", key: "space1" },
{
type: "collapse",
name: "Services",
key: "services",
icon: <Shop size="12px" />,
href: "https://github.com/creativetimofficial/ct-soft-ui-dashboard-pro-material-ui/blob/main/CHANGELOG.md",
component: Default,
noCollapse: true,
},
{
type: "collapse",
name: "Products",
key: "products",
icon: <Shop size="12px" />,
href: "https://github.com/creativetimofficial/ct-soft-ui-dashboard-pro-material-ui/blob/main/CHANGELOG.md",
component: Default,
noCollapse: true,
},
];
export default routes;
code used in main jsx file. I want to be able to write to the remote array changing its values.
const handleSubmit = (event) => {
event.preventDefault();
// I want to push or filter with the code below
{
routes.length = 0;
routes.map((route) => console.log({ route }));
}
};

You can't change the array itself because it's a const. You could change it to a let and then export it like this:
EDIT
export let routes = [
{
type: "collapse",
name: "Our Mission",
key: "dashboards",
icon: <Shop size="12px" />,
collapse: [
{
name: "Ways We can Help",
key: "default",
route: "/dashboards/default",
component: Default,
},
{
name: "How It Works",
key: "automotive",
route: "/dashboards/automotive",
component: Automotive,
},
{
name: "Who We Are",
key: "smart-home",
route: "/dashboards/smart-home",
component: SmartHome,
},
],
},
{ type: "title", title: " ", key: "space1" },
{
type: "collapse",
name: "Services",
key: "services",
icon: <Shop size="12px" />,
href: "https://github.com/creativetimofficial/ct-soft-ui-dashboard-pro-material-ui/blob/main/CHANGELOG.md",
component: Default,
noCollapse: true,
},
{
type: "collapse",
name: "Products",
key: "products",
icon: <Shop size="12px" />,
href: "https://github.com/creativetimofficial/ct-soft-ui-dashboard-pro-material-ui/blob/main/CHANGELOG.md",
component: Default,
noCollapse: true,
},
];
Then to use it in another jsx component you can import it like this.
import {routes} from '../yourPathToIt/main'
