Checking a sift filter

If the filter is valid the function returns true.

const siftFilter = {
  name: {
    $or: [{$eq: 'Max'}, {$eq: 'Moritz', age: 13}]
  }
};
 
const allowedAttributes = ['name', 'age'];
 
valid(siftFilter, ...allowedAttributes); // => true

If you pass a filter with a not allowed attribute it returns false.

const siftFilter = {
  id: {
    $or: [{$eq: 12}, {$eq: 13}]
  }
};
valid(siftFilter, ...allowedAttributes); // => false

If you pass a filter with an invalid operator it returns false.

const siftFilter = {
  id: {
    $or: [{$eq: 12}, {$nope: 13}]
  }
};
valid(siftFilter); // => false
