How to remove useless array and indexOf : I want to refactor this code without indexOf() and remove useless groupArr. I want to use ^ES6 or/and lodash

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

        const keys= ['activity', 'admin'];
        const labels = ["accountTypes.GROUP_ACCOUNT",
        "accountTypes.SINGLE_ACCOUNT",
        "activity.active",
        "activity.inactive",
        "admin.dictionaries.name",
        "admin.group.details.addedDate",
        "admin.group.details.enterDescription"];

        let arr = [];
        keys.forEach( key => {
          labels.forEach(label => {
            if (label.indexOf(key) === 0){
              arr.push(label);
            }
          });
        });

        console.log(arr)
