How to compare two routes by hand - vue.js

Question

How can I manually (programmatically) compare two routes and find out if they are same? (if router-link-active or router-link-exact-active would be present)
Generally i need this sort of a function
/*
#params route1, route2 : Route
*/
function isActivated(route1, route2) {
/* comparing them somehow */
return {
exactActive,
active
};
}
Use Case:
I have a NestedLink.vue component which is wrapper over router-link.
It takes to prop just as router-link (and passes it down to child router-link). If current route is active, nested links will apear nearby.
My approach:
function isActivated(route1, route2) {
if (
route1.matched.some(record =>
record.regex.test(route2.fullPath)
)
) {
return { exactActive: true };
}
return { exactActive: false };
}
It may tell when routes are exact-active but not for not-exact-active.

This is the code, used inside router-link component.
const START = '/';
const trailingSlashRE = /\/?$/;
function isObjectEqual (a, b) {
if ( a === void 0 ) a = {};
if ( b === void 0 ) b = {};
// handle null value #1566
if (!a || !b) { return a === b }
var aKeys = Object.keys(a);
var bKeys = Object.keys(b);
if (aKeys.length !== bKeys.length) {
return false
}
return aKeys.every(function (key) {
var aVal = a[key];
var bVal = b[key];
// check nested equality
if (typeof aVal === 'object' && typeof bVal === 'object') {
return isObjectEqual(aVal, bVal)
}
return String(aVal) === String(bVal)
})
}
function isSameRoute (a, b) {
if (b === START) {
return a === b
} else if (!b) {
return false
} else if (a.path && b.path) {
return (
a.path.replace(trailingSlashRE, '') === b.path.replace(trailingSlashRE, '') &&
a.hash === b.hash &&
isObjectEqual(a.query, b.query)
)
} else if (a.name && b.name) {
return (
a.name === b.name &&
a.hash === b.hash &&
isObjectEqual(a.query, b.query) &&
isObjectEqual(a.params, b.params)
)
} else {
return false
}
}
So, here's how to use it inside component:
// OR JUST A STRING '/home'
let link = { name: 'home' }
// will return true of false
let result = isSameRoute(this.$router.resolve(link).resolved, this.$route)
