Improve a function

Question

// Given an input of array, 
// which is made of items with >= 3 properties

let items = [
  {color: 'red', type: 'tv', age: 18}, 
  {color: 'silver', type: 'phone', age: 20},
  {color: 'blue', type: 'book', age: 17}
] 

// an exclude array made of key value pair
const excludes = [ 
  {k: 'color', v: 'silver'}, 
  {k: 'type', v: 'tv'}, 
  ...
] 

function excludeItems(items, excludes) { 
  excludes.forEach( pair => { 
    items = items.filter(item => item[pair.k] === item[pair.v])
  })
 
  return items
} 

1. What does this function excludeItems do?
2. Is this function working as expected ?
3. What is the time complexity of this function?
4. How would you optimize it ?

note

we only judge by the result, not the time cost. please submit the best approach you can.

Code

/**
 * @param {object[]} items
 * @excludes { Array< {k: string, v: any} >} excludes
 */

/**
 * @param {object[]} items
 * @param { Array< {k: string, v: any} >} excludes
 * @return {object[]}
 */
function excludeItems(items, excludes) {
  
}
