AngularJS filter where checking if array parameter contains value

I have simple function to set active state for nav based on url:

angular.forEach(this.$filter('filter')(this.fullNav, {
    'link': this.$location.$$path
}, true), (item) => {
    item.active = true;
});

Now I want to add legacy URLs to be also highlighted. Instead of link I have links (if there are more then one, but I can make all links parameters to be arrays.

To have it work with links and link paramaters I made change to this:

angular.forEach(this.fullNav, (item) => {
    if(item.links) {
        if(item.links.includes(this.$location.$$path)) {
            item.active = true;
        }
    } else {
        if(item.link === this.$location.$$path) {
            item.active = true;
        }
    }
});

How can I write the second function in $filter form? Or at least without if else statement (by removing link property and having only links property).

you can try following code which is similar to the code you have added.

angular.forEach(this.$filter('filter')(this.fullNav, (item) => {
    return Array.isArray(item.links) && item.links.includes(this.$location.$$path);
}, true), (item) => {
    item.active = true;
});
