I am trying to assign a score to each user submitted post as I a retrieve it from my mongo db. I go through the whole process and successfully add a 'score' property in my new array of posts objects. Now, I want to sort the posts based on that score. I am trying to use a simple compare function but it seems my code isnt even hitting this function.
I am not getting errors or anything printed to the console. All I get is my posts object in an array with a score property assigned.
Why is my code skipping over this sort function?
Thank you in advance.
postDB.connect
.then(db => db.collection("posts").find().forEach(function(posts) {
var postsArr = [];
postsArr.push(posts);
function generateScore(postWithoutScore) {
var timeSince = (((Date.now()/1000) - postWithoutScore.e) * 0.000277778);
var hh = ((postWithoutScore.upvote - 1)/Math.pow(timeSince + 2, 1.8)).toFixed(2);
return hh;
}
var postsWithScore = postsArr.map(function(post) {
// console.log(post);
return Object.assign({}, post, {
score: generateScore(post)
})
});
postsWithScore.sort(function (a, b){
console.log(b);
console.log(a);
return b[i].score - a[i].score;
});
console.log(postsWithScore);
})
.then(posts => {
console.log(posts);
res.render("projects", {
posts: posts
})
})
.catch(next))
});
