Array and array of objects

Question

I have an array and an array of objects

'neededPermissions: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]',

'permissions:[{permissionType: 1, teamId: 1},{permissionType: 4, teamId: 1},{permissionType: 7, teamId: 1},{permissionType: 8, teamId: 1},{permissionType: 10, teamId: 1}]'

// route with neededPermissions array must include with the permissions in current user, then the user will have access to the route // permissions.includes(neededPermissions)=true => user have access to the route

I know how it works for two arrays, but How to work with array and array of objects?

You may need to do custom filteration based on array of objects,

let resultPermissions = permissions.filter((x)=>{ 
 return neededPermissions.includes(x.permissionType)
})

for the above example, resultPermission should return false, right? because permissions array does not have all the permissions in neededPermissions array.

you can apply negation in front of includes method result

const permissions = [{permissionType: 1, teamId: 1},{permissionType: 4, teamId: 1},{permissionType: 7, teamId: 1},{permissionType: 8, teamId: 1},{permissionType: 10, teamId: 1}];
const neededPermissions = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];
const validPermissions = permissions.filter((item) => {
    return neededPermissions.includes(item.permissionType);
});

// returned matched permissions
console.log(validPermissions);

So, can I check whether the validPermissions===neededPermissions, then router should go to certain page. Will this work? if (validPermissions === to.meta.neededPermissions) { router.push({path:'/somePage'}) }

You need to make both data same. Array can't be compared like this. They share address rather than value in assignment. Another way can be: let mappedValidPermissions = validPermissions.map((item) => { return item.permissionType; }); Now can be compared as below: JSON.stringify(mappedValidPermissions) === JSON.stringify(neededPermissions);
