Promises and Their Valuable Variables

Recently I began learning JavaScript and I'm encountering some confusion.

Here's the code snippet that is causing me trouble:

api.posts
  .browse({ limit: 5, include: 'tags,authors' })
  .then(posts => {
    posts.forEach(post => {
      console.log(post.title)
    })
  })
  .catch(err => {
    console.error(err)
  })

While this code works perfectly fine and displays 5 post titles in the console. However, I need to implement a template like this:

<article v-for="post in posts" :key="post">
  <h2>{{ post.title }}</h2>
</article>

Unfortunately, "posts" cannot be accessed as a variable. I attempted to define variables inside ".then" but ran into errors. This might seem like elementary knowledge, but I haven't found a straightforward solution yet. I appreciate any help.

Answer №1

To effectively handle promises, it is recommended to declare a variable or property outside the promise chain. This variable can then be assigned the value when the promise is resolved. Here's an example:

api.posts
  .browse({ limit: 5, include: 'tags,authors' })
  .then(response => vm.data.posts = response)
