want to filter an array

April 28, 2022

I want to get an array with filtered values.
My arrays are like,

let arr=[{name:'trt,tet', id:5},{name:td, id:25},{name:fxg, id:1},{name:fs, id:4},{name:ste, id:41}]

let arr1 =[{data:fxg, addr:po 87987},{data:tert, addr:po8798fvd7},{data:trt, addr:po 887},{data:trhd, addr:po 8798787}]

my resultant array that I want is,

let rslt =[data:tert, addr:po8798fvd7},{data:trhd, addr:po 8798787}]

that is in arr the object ‘name’ which is also in arr1 with name ‘data’ I don’t need that array. nd some of which contain more than one name. I want to filter it.

>Solution :

try this

let arr=[{name:'trt,tet', id:5},{name:'td', id:25},{name:'fxg', id:1},{name:'fs', id:4},{name:'ste', id:41}]
let arr1 =[{data:'fxg', addr:'po 87987'},{data:'tert', addr:'po8798fvd7'},{data:'trt', addr:'po 887'},{data:'trhd', addr:'po 8798787'}]


const names = arr.flatMap(a => a.name.split(','))

const res = arr1.filter(a => !names.includes(a.data))

console.log(res)
