Answer

I would move away from class based react components as the functional style is recommended. You are not doing any sorting within inside your mapping of posts, this is why it is not working. Where you do your this.state.posts.map, I would chain that with a filter to remove the posts you don’t want. So it would be something like this:

this.state.posts
        .filter(post => post.includes('Y'))
        .map(post => ...)
