nodejs - cache data into an object or array

I'm trying to cache some informations in a node CLI script using an array or an object. I want to have a simple key value that I can ckeck to get usernames using the id that I want to use as the key. I'm trying with this code but I'm not sure if it will work as expected

let threads = [];
ig.realtime.on('message', async (data) => { 
    if( String(data.message.user_id) === ig.state.cookieUserId ){
        return;
    } else if ( data.message.path.endsWith('has_seen') ){
        return;
    } else if( !threads.includes(data.message.thread_id) ){
        const thread = await ig.feed.directThread({thread_id: data.message.thread_id}).request();
        threads[thread.thread.thread_id] = {
            username: thread.thread.users[0].full_name,
        }
    } 
});

Will the threads[thread.thread.thread_id] add the id as key each time that it will not be found into the array or I need to use Array.push() function?

Can I access to the key of the array in this way threads[data.message.thread_id] to get the related value?

use

if(!threads.find(o=>o.id==id)){
    threads.push({id, ...})
}

or simply use Map() as bellow

let threads = new Map();

if(!threads.has(id)){
   threads.set(id, value)
}
