Angular2 typescript search multiply values in array from array

Question about searching values from array into another array. Example of arrays:

 items = [{"name":"Goran", "category":[0:3, 1:5]}, {"name":"Marko", "category":[0:5, 1:4]}]

 arr1 = ["5", "4", "3"]

Typescript try:

let result = items.filter(item => arr1.find(f => f == items.category))

and the result is none. Can you give me hint how can I do this in one line of code. Basically this is filter from template. I you can image an array of checkbox checking the values from json object. So I want to find values where from arr1 in object items.

Try to use index of :

let result = items.filter(item => {
    return arr1.indexOf(items.category) > -1        
})
