Combining values in nested objects with common properties


Combining values in nested objects with common properties

I wish this help you Use Array#reduce to collect the values into a Map, then use Map#values, and the spread syntax to convert back to an array:
code :
const data = [[{"indicator":"A","geom":"1","score":1},{"indicator":"A","geom":"2","score":2}],[{"indicator":"B","geom":"1","score":3},{"indicator":"B","geom":"2","score":4}]];

const result = [...[].concat(...data).reduce((map, o) => {
  const item = map.get(o.geom) || { geom: o.geom, indicator: [], score: [] }; // get the item from the map, or create a new one
  
  item.indicator.push(o.indicator);
  item.score.push(o.score);
  
  return map.set(o.geom, item); // set the item and return the map reference
}, new Map).values()]; // get the map values iterator, and use spread (...) to get an array

console.log(result);

I wish did fix the issue. It is not possible to sort the properties of an object, you can however sort an array:
code :
var merged = $.extend({}, a);
for (var prop in b) {
    if (merged[prop]) merged[prop] += b[prop];
    else merged[prop] = b[prop];
}
// Returning merged at this point will give you a merged object with properties summed, but not ordered.
var properties = [];
for (var prop in merged) {
    properties.push({
        name: prop,
        value: merged[prop]
    });
}
return properties.sort(function(nvp1, nvp2) {
    return nvp1.value - nvp2.value;
});

seems to work fine I have users array with their name, , use _.flatMap to flat nested objects
code :
_.chain(worklogResult.issues)
    .flatMap('fields.worklog.worklogs')
    .thru(function(spents) {
        return _.map(users, function(user) {
            return _.merge(user, {
                timeSpentSeconds: _.chain(spents)
                    .filter(['author.name', user.name])
                    .map('timeSpentSeconds')
                    .sum()
                    .value()
            })
        })
    })
    .value()

I hope this helps . Instead of obj1::class.memberProperties you need to use SomeClass::class.memberProperties, e.g.:
code :
override fun buildNavItem() {
    val obj1 = "Hello"
    val obj2 = 10
    val obj1Props = String::class.memberProperties
    val obj2Props = Int::class.memberProperties

    val commonPropertyPairs  = obj1Props.map { obj1Prop ->
        obj1Prop to obj2Props.find { obj2Prop -> obj1Prop.name == obj2Prop.name } }
            .filter { pair -> pair.second == null }

    commonPropertyPairs.forEach { pair ->
        pair.first.get(obj1)
    }
}

To fix the issue you can do I have a dataset, an array of objects, I need to combine by a common key (Date) and then merge the UserName as the key for the UserScore. I am planning to graph this data with d3 and have the solution using some of d3's methods but would like to write it with vanilla JS. Here is a sample of the raw data , You can use reduce() to group them.
code :
const arr = [ { "Date": "2019-05-02 00:00:00 UTC", "UserName": "user1", "UserScore": "39" }, { "Date": "2019-05-02 00:00:00 UTC", "UserName": "user2", "UserScore": "11" }, { "Date": "2019-05-02 00:00:00 UTC", "UserName": "user3", "UserScore": "4" }, { "Date": "2019-05-02 01:01:01 UTC", "UserName": "user1", "UserScore": "57" }, { "Date": "2019-05-02 01:01:01 UTC", "UserName": "user2", "UserScore": "1" }, { "Date": "2019-05-02 01:01:01 UTC", "UserName": "user3", "UserScore": "42" } ]

const res = arr.reduce((ac,{Date,UserName,UserScore}) => {
  ac[Date] = ac[Date] || {Date};
  ac[Date][UserName] = UserScore;
  return ac;
},{})

console.log(Object.values(res))

help you fix your problem So you can simply keep checking if the children key exists and update the object you are checking against. This can get as nested as you would like. I updated one of your routes to allow this to be shown more easily.
Basically
code :
const routes = [
  {
    path: '/system-settings1',
    name: 'global-settings1',
    component: 'tabs1',
    children: {
      path: 'CHILD1accounting1',
      name: 'local-settings1',
      components: 'modals1',
      children: {
        path: 'CHILD2accounting1',
        name: 'local-settings1',
        components: 'modals1'
        // more children deeply nested(or not)
      }
    }
  },
  {
    path: '/system-settings2',
    name: 'global-settings2',
    component: 'tabs2',
    children: {
      path: 'accounting2',
      name: 'local-settings2',
      components: 'modals2',
      children: {
        path: 'accounting1',
        name: 'local-settings1',
        components: 'modals1'
        // more children deeply nested(or not)
      }
    }
  },
  {
    path: '/system-settings3',
    name: 'global-settings3',
    component: 'tabs3',
    children: {
      path: 'accounting3',
      name: 'local-settings3',
      components: 'modals3',
      children: {
        path: 'accounting1',
        name: 'local-settings1',
        components: 'modals1'
        // more children deeply nested(or not)
      }
    }
  },
]



let x = routes.map(route => {
  let path = route.path + "/";
  while(route.hasOwnProperty('children')) {
    route = route.children;
    path += `${route.path}/`
  }
  return path;
});

console.log(x);
