underscore.js - create array of unique items from objects embedded in a list of objects


Tag : javascript , By : shenol

wish of those help Based on our conversation, it sounds like it would be better to compute this on the server via a method call. For educational purposes, here's how you could do it using underscore:
// Get an array of docs somehow
var docs = Collection.find().fetch();

var taggedUsers = _.chain(docs)
  .map(function(d) {
    // Copy the 'field' to each of the tagged users within a doc
    _.each(d.taggedUsers, function(user) {
      user.field = d.field;
    });
    return d;
  })
  .pluck('taggedUsers') // Extract only the tagged users arrays
  .flatten() // Flatten them into a single array
  .value();

// taggedUsers could look something like:
// [ { id: 1122244453, username: 'john123', field: 'ABC' },
//   { id: 1122244454, username: 'bill123', field: 'ABC' },
//   { id: 1122244455, username: 'jim123', field: 'ABC' },
//   { id: 1122244453, username: 'john123', field: 'ABC' } ]

// Compute a unique lists of tagged users, where the docs are unique by id
var utu = _.uniq(taggedUsers, false, function(user) {return user.id;});

How to pass objects of an array of objects as list of comma seperated objects to a function?

To fix this issue I'm using a function that expects a comma separated list of objects as parameters. What I actually have is an array of objects. , If your function is
function hello(obj1,obj2) {
}
hello.apply(this,my_array_of_objects)

hope this fix your issue I have a list of object. I want to make sublist from the arraylist.. according to the file size. , How about this:
public List<List<FileInfo>> partition(List<FileInfo> list, int maxSize) {
    List<List<FileInfo>> result = new ArrayList<>();
    List<FileInfo> current = new ArrayList<>();
    int currentSize = 0;
    for (FileInfo fi: list) {
        if (fi.getFileSize() > 0) {
            if (!current.isEmpty()
                    && currentSize + fi.getFileSize() > maxSize) {
                result.add(current);
                current = new ArrayList<>();
                currentSize = 0;
            }
            current.add(fi);
            currentSize += fi.getFileSize();
        }
    }
    if (!current.isEmpty()) {
        result.add(current);
    }
    return result;
}

Search the list of values in another array of objects and change the one key in array of objects using single for loop


Tag : javascript , By : Paul Schwarz

With these it helps I want to change the 'selected' key value in emps, if the empIds are available. I tried the below logic using two for loops. I was trying the logic using single for loop, but it didn't work. Any one has some idea on single for loop logic. Please give some sample logic on it. , Simple forEach and includes
const empIds = [1, 3];

// object values in array are dynamic
const emps = [{
    id: 1,
    name: 'test1',
    selected: false
  },
  {
    id: 2,
    name: 'test2',
    selected: false
  },
  {
    id: 3,
    name: 'test3',
    selected: false
  }
];

emps.forEach(e => e.selected = empIds.includes(e.id));

console.log(emps);
