[Solved] need to create new array called result with key/value from posts and inside that reviews array with user and comment key/value objects

Use map with filter:

let posts = [{
    "id": 101,
    "title": "Some post title"
  },
  {
    "id": 102,
    "title": "Some Another post title"
  },
  {
    "id": 103,
    "title": "Some Best post title ever"
  }
]

let reviews = [{
    "postId": 101,
    "user": "Chris",
    "comment": "Great post!"
  },
  {
    "postId": 101,
    "user": "Jason",
    "comment": "Worth reading."
  },
  {
    "postId": 102,
    "user": "Dave",
    "comment": "Waste of time"
  }
]

const res = posts.map(({
  id,
  title
}) => ({
  id,
  title,
  reviews: reviews.filter(({
    postId
  }) => postId == id).map(({
    user,
    comment
  }) => ({
    user,
    comment
  }))
}));

console.log(res);
