Having issues using a local filter with v-for and encountering an error
Error message: Property or method "filterByTitle" is not defined on the instance but referenced during render. Ensure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

<ul class="blog-list-single" v-for="(post, index) in posts | filterByTitle" :key="index">
<li class="title">{{ post.title }}</li>
<li class="author">{{ post.author }}</li>
</ul>
