I have two arrays of objects, one array contains objects that represent user data.
const userData = [
{
user_name: "Tania",
email: "[email protected]",
partido: "8",
categoria_1: "1",
categoria_2: "2",
categoria_3: null
},
{
user_name: "Jean",
email: "[email protected]",
partido: "24",
categoria_1: null,
categoria_2: "2",
categoria_3: null
},
{
user_name: "Vania",
email: "[email protected]",
partido: "13",
categoria_1: null,
categoria_2: "2",
categoria_3: null
},
{
user_name: "Rick",
email: "[email protected]",
partido: "13",
categoria_1: "1",
categoria_2: "2",
categoria_3: "3"
}
],
A second array contains objects that represent collections.
collectionData = [
{
partido: "8",
Equipo_Local: "Argentina",
Equipo_Visitante: "Arabia SaudÃ",
categoria_1: "1",
categoria_2: "No dis",
categoria_3: "No dis"
},
{
partido: "24",
Equipo_Local: "Argentina",
Equipo_Visitante: "México",
categoria_1: "No dis",
categoria_2: "2",
categoria_3: "No dis"
},
{
partido: "13",
Equipo_Local: "Polonia",
Equipo_Visitante: "Argentina",
categoria_1: "No dis",
categoria_2: "2",
categoria_3: "3"
}
];
Features
- All objects in both arrays include the properties:
"partido", "category_1", "category_2", "category_3", but can include more properties. - The Listed properties change their values dynamically.
My starting point is to store each listed property in independent variables.
On the next line, pass as arguments the arrays where I want to find and match the specifics keys. Start with "partido" property searching in both arrays for the first match, if it finds the match or matches, it returns a new array of objects with the matches found for that property.
Start by looping through each objects in userData and dataCollection arrays. In this case,
I search for matches using each key in both object arrays. And I get two matches partido: "8" and partido: "13", then store that matches inside the new variable named matchPartido array and return matchPartido.
const checkPartido = ["partido"]
const checkCategoria_1 = ["categoria_1"]
const checkCategoria_2 = ["categoria_2"]
const checkCategoria_3 = ["categoria_3"]
function getMatches(
first,
second,
checkPartido,
checkCategoria_1,
checkCategoria_2,
checkCategoria_3) {
let finalMatches = []
let matchPartido = []
let matchCat_1 = []
let matchCat_2 = []
let matchCat_3 = []
first.forEach((userMatch) => {
second.forEach((collection) => {
const isMatchPartido = checkPartido.every((key) => {
return collection[key] === userMatch[key];
});
if (
isMatchPartido &&
!matchPartido.find((match) => match === userMatch)
) {
matchPartido.push(userMatch);
}
});
});
Now I go for the next match, which is category_1, categoria_2 and categoria_3 properties stored in the variables named checkCategory_1, checkCategory_2, checkCategory_3.
matchPartido.forEach((userMatch) => {
second.forEach((newCollection) => {
const isMatchCategory = checkCategoria_1.every((key) => {
return newCollection[key] === userMatch[key]
});
if (
isMatchCategory &&
!matchCat_1.find((match) => {
return match === userMatch
})
) {
matchCat_1.push(userMatch)
//console.log(matchCat_1)
return matchCat_1
}
});
});
matchCat_1.forEach((userMatch) => {
second.forEach((newCollection) => {
const isMatchCategory = checkCategoria_2.every((key) => {
return newCollection[key] === userMatch[key]
});
if (
isMatchCategory &&
!matchCat_2.find((match) => {
return match === userMatch
})
) {
matchCat_2.push(userMatch)
//console.log(matchCat_2)
return matchCat_2
}
});
});
matchCat_2.forEach((userMatch) => {
second.forEach((newCollection) => {
const isMatchCategory = checkCategoria_3.every((key) => {
return newCollection[key] === userMatch[key]
});
if (
isMatchCategory &&
!matchCat_3.find((match) => {
return match === userMatch
})
) {
matchCat_3.push(userMatch)
//console.log(matchCat_3)
return matchCat_3
}
});
});
return (finalMatches = [...matchCat_1, matchCat_2, matchCat_3])
}
console.log(
getFirstMatches(
userData,
collectionData,
checkPartido,
checkCategoria_1,
checkCategoria_2,
checkCategoria_3
)
)
That's work OK... BUT.
I need to return an array of matched for partido 8
Now i have one match for `partido:"8"`, I mean only one user pick `partido: "8"` then check if categoria_1 property match, if not go categoria_2 and last categoria_3, there is one match categoria_1 property and return the array like the following.[
{
user_name: "Tania"
email: "[email protected]"
partido: "8"
categoria_1: "1"
},{},{}...
]
Then for partido 24
Now i have one match for `partido:"24"`, I mean only one user pick `partido: "24"` then check if categoria_1 property match, if not, go categoria_2 and last categoria_3, there is one match categoria_2 property and return the array like the following.[
{
user_name: "Jean"
email: "[email protected]"
partido: "24",
categoria_2: "2",
},{},{}...
]
And last for partido 13
Now i have two matches for `partido:"13"`, I mean two users pick `partido: "13"` then check if categoria_1 property match, if not go categoria_2 and last categoria_3, there is two matches categoria_2 and categoria_3 properties and return the array like the following.[
{
user_name: "Vania",
email: "[email protected]",
partido: "13",
categoria_3: "3"
},
{
user_name: "Rick",
email: "[email protected]",
partido: "13",
categoria_2: "2"
},
,
{
user_name: "Rick",
email: "[email protected]",
partido: "13",
categoria_3: "3"
},
{}, {}, {}...
]

Maybe you're looking for something like a modified 'group by'? Here reducing collectionData and aggregating matching results from userData by relevant partido and cateoria_ into the result object.
const userData = [{ user_name: "Tania", email: "[email protected]", partido: "8", categoria_1: "1", categoria_2: "2", categoria_3: null }, { user_name: "Jean", email: "[email protected]", partido: "24", categoria_1: null, categoria_2: "2", categoria_3: null }, { user_name: "Vania", email: "[email protected]", partido: "13", categoria_1: null, categoria_2: "2", categoria_3: null }, { user_name: "Rick", email: "[email protected]", partido: "13", categoria_1: "1", categoria_2: "2", categoria_3: "3" }];
const collectionData = [{ partido: "8", Equipo_Local: "Argentina", Equipo_Visitante: "Arabia SaudÃ", categoria_1: "1", categoria_2: "No dis", categoria_3: "No dis" }, { partido: "24", Equipo_Local: "Argentina", Equipo_Visitante: "México", categoria_1: "No dis", categoria_2: "2", categoria_3: "No dis" }, { partido: "13", Equipo_Local: "Polonia", Equipo_Visitante: "Argentina", categoria_1: "No dis", categoria_2: "2", categoria_3: "3" }];
const result = Object.values(
collectionData.reduce((res, { partido, ...rest }) => {
res[partido] ??= { partido, ...rest, userData: {} }
for (const cat of ['categoria_1', 'categoria_2', 'categoria_3']) {
if (rest[cat] !== 'No dis') {
(res[partido].userData[cat] ??= [])
.push(...userData
.filter(u => u.partido === partido && u[cat] === rest[cat])
.map(u => ({ ...u }))
)
}
}
return res;
}, {})
);
console.log(result)
