Spinning my wheels here. Seems simple conceptually but JS is trying to kill me.
Two arrays of objects:
let allProfileUsers = [
{
id: "0b4cd920-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
active: true
},
{
id: "0b4f9840-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea73670-31ac-11ec-81f6-9b65b19a8154",
active: true
},
{
id: "0b51e230-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
active: true
}
];
let allAuthUsers = [
{
id: "fea4c570-31ac-11ec-81f6-9b65b19a8154",
username: "user1",
active: true,
},
{
id: "fea73670-31ac-11ec-81f6-9b65b19a8154",
username: "user2",
active: true,
},
{
id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
username: "user3",
active: true,
}
];
I need to compare the "id" field in the objects in the first array to the "auth_user_id" field in the second set of arrays. Basically, all users in array one should exist in array two, based on the match-up of those two fields.
This doesn't work (not shorthand so it's easy to debug):
let allMatched = allAuthUsers.every(x => {
return allProfileUsers.some(pu => {
return x.id === pu.auth_user_id;
});
});
...returns false;
Of course, I could manually loop through each value and compare them. I don't want that unless there's no other way.
I have to think JS is capable of a more elegant one-liner with arrows. In fact, frustratingly, I know I've done this before, but I just can't seem to make it happen today.
Buddy, I feel the answer is in your question. You need to loop through the first array(allProfileUsers) first and then check if it exist in second(allAuthUsers).
let allMatched = allProfileUsers.every(pu => {
return allAuthUsers.some(x => {
return x.id === pu.auth_user_id;
});
});
Try some thing like below. Process one of array values to Set and use it another array every method.
let allProfileUsers = [
{
id: "0b4cd920-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
active: true,
},
{
id: "0b4f9840-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea73670-31ac-11ec-81f6-9b65b19a8154",
active: true,
},
{
id: "0b51e230-31da-11ec-a31c-cd844bfb73be",
auth_user_id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
active: true,
},
];
let allAuthUsers = [
{
id: "fea4c570-31ac-11ec-81f6-9b65b19a8154",
username: "user1",
active: true,
},
{
id: "fea73670-31ac-11ec-81f6-9b65b19a8154",
username: "user2",
active: true,
},
{
id: "fea98060-31ac-11ec-81f6-9b65b19a8154",
username: "user3",
active: true,
},
];
const auth = new Set(allAuthUsers.map(({ id }) => id));
const isExist = allProfileUsers.every(({ auth_user_id }) =>
auth.has(auth_user_id)
);
console.log(isExist)
