Need to filter the arr based on check values. I am unable to filter inside the getItems function.
let check = ["DIS_1","DIS_2","DIS_6","DIS_10"]
let arr = [{otherProperty: "",cr: [{cc: "DIS_1", cv: "cal1"},{cc: "first", cv: "cal2"},{cc: "DIS_2", cv: "cal3"}]},
{otherProperty: "",cr: [{cc: "DIS_6", cv: "cal4"},{cc: "second", cv: "cal5"},{cc: "DIS_10", cv: "cal6"}]},
{otherProperty: "",cr: [{cc: "third", cv: "cal7"},{cc: "fourth", cv: "cal8"},{cc: "DIS_1", cv: "cal9"}]}
]
let expectedOutput = [{otherProperty: "",cr: [{cc: "DIS_1", cv: "cal1"},{cc: "DIS_2", cv: "cal3"}]},
{otherProperty: "",cr: [{cc: "DIS_6", cv: "cal4"},{cc: "DIS_10", cv: "cal6"}]},
{otherProperty: "",cr: [{cc: "DIS_1", cv: "cal9"}]}
]
function getItems(arr) {
console.log('--arr', arr)
}
console.log('expect', getItems(arr))You can do it with one liner:
const getItems = (arr) => arr.map(({cr, ...other_properties})=> ({ ...other_properties, cr: cr.filter(item=>check.includes(item.cc))}));
Here is the working example:
let check = ["DIS_1","DIS_2","DIS_6","DIS_10"]
let arr = [
{otherProperty: "",cr: [{cc: "DIS_1", cv: "cal1"},{cc: "first", cv: "cal2"},{cc: "DIS_2", cv: "cal3"}]},
{otherProperty: "",cr: [{cc: "DIS_6", cv: "cal4"},{cc: "second", cv: "cal5"},{cc: "DIS_10", cv: "cal6"}]},
{otherProperty: "",cr: [{cc: "third", cv: "cal7"},{cc: "fourth", cv: "cal8"},{cc: "DIS_1", cv: "cal9"}]}
]
const getItems = (arr) => arr.map(({cr, ...other_properties})=> ({ ...other_properties, cr: cr.filter(item=>check.includes(item.cc))}));
console.log(getItems(arr));// let check = ["DIS_1","DIS_2","DIS_6","DIS_10"];
let type = { DIS_1: "first", DIS_2: "two", DIS_6: "six", DIS_10: "ten" };
let arr = [{otherProperty: "",cr: [{cc: "DIS_1", cv: "cal1"},{cc: "first", cv: "cal2"},{cc: "DIS_2", cv: "cal3"}]},
{otherProperty: "",cr: [{cc: "DIS_6", cv: "cal4"},{cc: "second", cv: "cal5"},{cc: "DIS_10", cv: "cal6"}]},
{otherProperty: "",cr: [{cc: "third", cv: "cal7"},{cc: "fourth", cv: "cal8"},{cc: "DIS_1", cv: "cal9"}]}
]
// using array
// const res = arr.map(item => ({...item, cr : item.cr.filter(o => check.includes(o.cc))}));
// using object
const res = arr.map(item => ({...item, cr : item.cr.filter(o => Object.keys(type).includes(o.cc))}));
console.log(res);.as-console-wrapper { max-height: 100% !important; top: 0 }
