I have an array of objects that looks like this:
"data": [
{ "workout_id": 1, "user_id": 1, "shotLocation": 27, "shotAttempts": 20,"shotsMade": 19, "id": 1 },
{ "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 2 },
{ "workout_id": 2, "user_id": 1, "shotLocation": 10, "shotAttempts": 10, "shotsMade": 7, "id": 3 },
{ "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 29, "id": 4 },
{ "workout_id": 3, "user_id": 5, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 5 },
{ "workout_id": 4, "user_id": 6, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 15, "id": 6 },
{ "workout_id": 4, "user_id": 6, "shotLocation": 2, "shotAttempts": 20, "shotsMade": 14, "id": 7 }
]
I would like to create a new array of objects where I
reduce the user_ids to each unique user
then calculate the total shotAttempts and shotsMade for each user
like this:
"dataTotals" : [
{"id": 1, "user_id": 1, "shotAttempts": 90, "shotsMade": 64}
{"id": 2, "user_id": 5, "shotAttempts": 10, "shotsMade": 9}
{"id": 3, "user_id": 6, "shotAttempts": 50, "shotsMade": 29}
I plan on iterating over this new array of objects with a .map function to populate a leaderboard as more users record their data.
I've tried several different ways to achieve this based on what I've read about the .map and .reduce methods, as well as searching here and found something that's close, but it returns an object as indicated below.
like this:
// create new object to store results in
let newObj = {};
// loop through user objects
this.state.shotlogs.forEach(function(shotlog){
// check if user_id has already been added to newObj
if(!newObj[shotlog.user_id]){
// If it is the first time seeing this user_id
// we need to add shots attempted and shots made to prevent errors
newObj[shotlog.user_id] = {};
newObj[shotlog.user_id]['user_id'] = shotlog.user_id;
newObj[shotlog.user_id]['shotAttempts'] = 0;
newObj[shotlog.user_id]['shotsMade'] = 0;
}
// add shots attempted and made to newObj for this user
newObj[shotlog.user_id]['shotAttempts'] += shotlog.shotAttempts
newObj[shotlog.user_id]['shotsMade'] += shotlog.shotsMade
})
but this returns an object that looks like this and not an array of objects like above:
{
1: {user_id: 1, shotAttempts: 70, shotsMade: 64}
5: {user_id: 5, shotAttempts: 10, shotsMade: 9}
6: {user_id: 6, shotAttempts: 50, shotsMade: 29}
}
Any help for this new coder is greatly appreciated!!
const data = [
{ workout_id: 1, user_id: 1, shotLocation: 27, shotAttempts: 20, shotsMade: 19, id: 1 },
{ workout_id: 2, user_id: 1, shotLocation: 1, shotAttempts: 10, shotsMade: 9, id: 2 },
{ workout_id: 2, user_id: 1, shotLocation: 10, shotAttempts: 10, shotsMade: 7, id: 3 },
{ workout_id: 2, user_id: 1, shotLocation: 1, shotAttempts: 30, shotsMade: 29, id: 4 },
{ workout_id: 3, user_id: 5, shotLocation: 1, shotAttempts: 10, shotsMade: 9, id: 5 },
{ workout_id: 4, user_id: 6, shotLocation: 1, shotAttempts: 30, shotsMade: 15, id: 6 },
{ workout_id: 4, user_id: 6, shotLocation: 2, shotAttempts: 20, shotsMade: 14, id: 7 }
];
const shooters = data.reduce(
(results, current) => ({
...results,
[current.user_id]: {
user_id: current.user_id,
shotAttempts: current.shotAttempts + (results[current.user_id] ? results[current.user_id].shotAttempts : 0),
shotsMade: current.shotsMade + (results[current.user_id] ? results[current.user_id].shotsMade : 0)
}
}),
{}
);
console.log(shooters);
You can use Array.reduce, Object.values with ES6 destructuring and solve this in a concise manner:
const data = [{ "workout_id": 1, "user_id": 1, "shotLocation": 27, "shotAttempts": 20, "shotsMade": 19, "id": 1 }, { "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 2 }, { "workout_id": 2, "user_id": 1, "shotLocation": 10, "shotAttempts": 10, "shotsMade": 7, "id": 3 }, { "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 29, "id": 4 }, { "workout_id": 3, "user_id": 5, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 5 }, { "workout_id": 4, "user_id": 6, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 15, "id": 6 }, { "workout_id": 4, "user_id": 6, "shotLocation": 2, "shotAttempts": 20, "shotsMade": 14, "id": 7 } ]
const result = data.reduce((r,{workout_id, user_id, shotAttempts, shotsMade}) => {
r[user_id] = r[user_id] || {id: workout_id, user_id, shotAttempts: 0, shotsMade: 0}
r[user_id].shotAttempts += shotAttempts
r[user_id].shotsMade += shotsMade
return r
}, {})
console.log(Object.values(result))
You can use Array.prototype.reduce()
Code:
const data = [{ "workout_id": 1, "user_id": 1, "shotLocation": 27, "shotAttempts": 20,"shotsMade": 19, "id": 1 },{ "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 2 },{ "workout_id": 2, "user_id": 1, "shotLocation": 10, "shotAttempts": 10, "shotsMade": 7, "id": 3 },{ "workout_id": 2, "user_id": 1, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 29, "id": 4 },{ "workout_id": 3, "user_id": 5, "shotLocation": 1, "shotAttempts": 10, "shotsMade": 9, "id": 5 },{ "workout_id": 4, "user_id": 6, "shotLocation": 1, "shotAttempts": 30, "shotsMade": 15, "id": 6 },{ "workout_id": 4, "user_id": 6, "shotLocation": 2, "shotAttempts": 20, "shotsMade": 14, "id": 7 }];
const dataTotals = Object.values(data.reduce((a, c) => {
if (!a[c.user_id]) {
a[c.user_id] = {
id: c.workout_id,
user_id: c.user_id,
shotAttempts: c.shotAttempts,
shotsMade: c.shotsMade
};
} else {
a[c.user_id].shotAttempts += c.shotAttempts;
a[c.user_id].shotsMade += c.shotsMade;
}
return a;
}, {}));
console.log(dataTotals);

I already tried to convert the array (as you can see in my Code), but the problem is that my D3 chart expects a JSON object, but by my attempt no json object is passed anymore.
Can anyone help me with this?
I would be very grateful for any advice!
I have data like this:
let data = []
let weeks = [
{
"week": 1,
"crop": {
"aop": 1,
"actual": 2,
"kbm": 3
},
"hk": {
"aop": 4,
"actual": 5,
"kbm": 6
},
"outputHkAct": 7
},
{
"week": 2,
"crop": {
"aop": 11,
"actual": 12,
"kbm": 13
},
"hk": {
"aop": 14,
"actual": 15,
"kbm": 16
},
"outputHkAct": 17
},
]
i wanth to merge & get the value every week in crop(aop, actual, kbm), outputHkAct , hk(aop, actual, kbm), outputHkAct.
the output should be :
data = [1, 2, 3, 4, 5, 6, 7, 11, 12, 13, 14, 15, 16, 17]
anyone can help? thanks guys.
It can be solved by using forEach:
let data = []
let weeks = [
{
"week": 1,
"crop": {
"aop": 1,
"actual": 2,
"kbm": 3
},
"hk": {
"aop": 4,
"actual": 5,
"kbm": 6
},
"outputHkAct": 7
},
{
"week": 2,
"crop": {
"aop": 11,
"actual": 12,
"kbm": 13
},
"hk": {
"aop": 14,
"actual": 15,
"kbm": 16
},
"outputHkAct": 17
},
]
weeks.forEach(({crop,hk,outputHkAct})=>{
data.push(crop.aop);
data.push(crop.actual);
data.push(crop.kbm);
data.push(hk.aop);
data.push(hk.actual);
data.push(hk.kbm);
data.push(outputHkAct)
})
console.log(data)
You can suer for in loop which helps you to loop through an object
let weeks = [
{
"week": 1,
"crop": {
"aop": 1,
"actual": 2,
"kbm": 3
},
"hk": {
"aop": 4,
"actual": 5,
"kbm": 6
},
"outputHkAct": 7
},
{
"week": 2,
"crop": {
"aop": 11,
"actual": 12,
"kbm": 13
},
"hk": {
"aop": 14,
"actual": 15,
"kbm": 16
},
"outputHkAct": 17
},
]
let allValues = [];
weeks.map(obj=>{
for(let key in obj){
if(key === 'crop' || key === 'hk'){
for(let k in obj[key]){
allValues.push(obj[key][k])
}
}else if(key === 'outputHkAct'){
allValues.push(obj[key])
}
}
})
console.log(allValues)
weeks is an array of object.
So you have to iterate through weeks array (by using for-of, for-in, while, map, reduce, etc.) to get the object and now you can access the value of the object by using a key which you already know (crop(aop, actual, kbm), outputHkAct , hk(aop, actual, kbm), outputHkAct).
Here is the example by using reduce.
let weeks = [
{
"week": 1,
"crop": {
"aop": 1,
"actual": 2,
"kbm": 3
},
"hk": {
"aop": 4,
"actual": 5,
"kbm": 6
},
"outputHkAct": 7
},
{
"week": 2,
"crop": {
"aop": 11,
"actual": 12,
"kbm": 13
},
"hk": {
"aop": 14,
"actual": 15,
"kbm": 16
},
"outputHkAct": 17
},
];
let data = [...weeks.reduce((v, { crop, hk, outputHkAct }) => [...v, ...Object.values(crop), ...Object.values(hk), outputHkAct], [])];
console.log(data);
So i have this scope with a predefined equipment:
$scope.equipment = [
{slot: 7, colspan: 2, rowspan: 1},
{slot: 0, colspan: 2, rowspan: 2},
{slot: 10, colspan: 2, rowspan: 1},
{slot: 8, colspan: 1, rowspan: 1},
{slot: 9, colspan: 1, rowspan: 1},
{slot: 6, colspan: 2, rowspan: 1},
{slot: 17, colspan: 1, rowspan: 1},
{slot: 18, colspan: 1, rowspan: 1},
{slot: 1, colspan: 2, rowspan: 4},
{slot: 19, colspan: 2, rowspan: 1},
{slot: 4, colspan: 2, rowspan: 4},
{slot: 5, colspan: 2, rowspan: 4},
{slot: 14, colspan: 1, rowspan: 1},
{slot: 15, colspan: 1, rowspan: 1},
{slot: 2, colspan: 2, rowspan: 2},
{slot: 16, colspan: 1, rowspan: 1},
{slot: 15, colspan: 1, rowspan: 1},
{slot: 3, colspan: 2, rowspan: 2}
];
As you can see, each slot has its own colspan and rowspan.
Than i have the equipment items array of objects:
$scope.equipmentItems = [

},

"bind": 0,
"slot": 13
},
{

},

"slot": 18,
"name": "Killian's Ring",
"description": "This generates powerful energy from the combination of Killian's Dark Energy and the grudge of the Black Cat, the Guardian of Hell."
},

"bind": 0,
"slot": 19,
"name": "Belt of Damp +4",
"description": "This belt reduces damage from intensified sword or magic attacks. "
}
];
As you can see each object key is basically the slot id.
Than i use this code
$scope.equipmentItems = _.sortBy($scope.equipmentItems, function(obj) {
return _.indexOf([7, 0, 10, 8, 9, 6, 17, 18, 1, 19, 4, 5, 14, 13, 2, 16, 15, 3], obj.slot);
});
to sort the equipment items keys to my specific order.
Anyway, what i want is the most performant piece of code that can add the values colspan and rowspan from $scope.equipment to $scope.equipmentItems WHERE $scope.equipment slot correspond to $scope.equipmentItems slot.
You can use Array functions. Something like this:
let merged = equipmentItems.map(item=>{
item.anotherKey = equipment.find(it=> it.slot == item.slot);
return item;
});
If you don't like this, or you can't use those methods you can use forEach
equipmentItems.forEach(function(item){
equipment.forEach(function(item_){
if(item.slot == item_.slot){
item.someKey = item_;
}
});
});
Got this array:
var arr = [
{
series: [
{
"name": 2014,
"data": [19, 17, 15, 12, 10, 10, 12, 10, 11, 14, 14, 18]
},
{
"name": 2015,
"data": [18, 17, 16, 12, 10, 7, 6, 8, 8, 11, 15, 30]
},
]
},
{
series: [
{
"name": 2014,
"data": [32, 17, 15, 12, 33 10, 33, 10, 11, 14, 14, 18]
},
{
"name": 2015,
"data": [45, 10, 12, 55, 77, 7, 6, 8, 8, 11, 33, 30]
},
]
},
]
I need to create a function that returns a summrized series:
var series = [
{
year: '2014',
data: [51, 34....],
},
{
year: '2015',
data: [63, 27....],
}
]
I could to loops to do this but I guess there is some smart way of doing with underscore? Probably with the reduce function. Any ideas of how to do this?
var arr = [{
"series": [{
"name": 2014,
"data": [19, 17, 15, 12, 10, 10, 12, 10, 11, 14, 14, 18]
}, {
"name": 2015,
"data": [18, 17, 16, 12, 10, 7, 6, 8, 8, 11, 15, 30]
}]
}, {
"series": [{
"name": 2014,
"data": [19, 17, 15, 12, 10, 10, 12, 10, 11, 14, 14, 18]
}, {
"name": 2015,
"data": [18, 17, 16, 12, 10, 7, 6, 8, 8, 11, 15, 30]
}]
}];
_.chain(arr)
.map('series')
.flatten()
.reduce(function(object, value) {
object[value.name] = !object[value.name] ? value.data : _.union(object[value.data], value.data);
return object;
}, {})
.reduce(function(arr, value, key) {
arr.push({
year: key,
data: value
});
return arr;
}, [])
.value();
You could use some iterations and an object as reference to the year for grouping.
var arr = [{ series: [{ "name": 2014, "data": [19, 17, 15, 12, 10, 10, 12, 10, 11, 14, 14, 18] }, { "name": 2015, "data": [18, 17, 16, 12, 10, 7, 6, 8, 8, 11, 15, 30] }] }, { series: [{ "name": 2014, "data": [32, 17, 15, 12, 33, 10, 33, 10, 11, 14, 14, 18] }, { "name": 2015, "data": [45, 10, 12, 55, 77, 7, 6, 8, 8, 11, 33, 30] }] }],
series = [];
arr.forEach(function (a) {
Object.keys(a).forEach(function (k) {
a[k].forEach(function (b) {
if (!this[b.name]) {
this[b.name] = { year: b.name, data: [] };
series.push(this[b.name]);
}
b.data.forEach(function (c, i) {
this[b.name].data[i] = (this[b.name].data[i] || 0) + c;
}, this);
}, this);
}, this);
}, {});
document.write('<pre>' + JSON.stringify(series, 0, 4) + '</pre>');
I'm trying to search in a array which contains PeriodicElements to Perodify a given name. This link
http://www.lmntology.com/ is what exactly what I want to do. But I can't find tune the search to
return Elements with two letters, Basically it returns the first match.
For example
"CARL" the generic search would return - Carbon, Adamantium, Rearden, Latinum
where as "CARL" should also return - Carbon, Argon ,Latinum
Any suggestions? Or a fiddle would be greatly appreciated.
