So I have an array
const records = [
{
value: 24,
gender: "BOYS"
},
{
value: 42,
gender: "BOYS"
},
{
value: 85,
gender: "GIRLS"
},
{
value: 12,
gender: "GIRLS"
},
{
value: 10,
gender: "BOYS"
}
]
And I want to get only "Boys" objects within an array using js reduce() rather than filter(). Please help.
const records = [
{
value: 24,
gender: "BOYS"
},
{
value: 42,
gender: "BOYS"
},
{
value: 85,
gender: "GIRLS"
},
{
value: 12,
gender: "GIRLS"
},
{
value: 10,
gender: "BOYS"
}
]
let boys = records.reduce((t,o)=>{
if(o.gender === "BOYS") t.push(o)
return t
},[])
console.log(boys)Уou can use any option you want
const records = [{value: 24,gender: "BOYS"},{value: 42,gender: "BOYS"},{value: 85,gender: "GIRLS"},{value: 12,gender: "GIRLS"},{value: 10,gender: "BOYS"}]
const withReduce = records.reduce((acc, item) => item.gender === "BOYS" ? [...acc, item] : acc, []);
const withFlatMap = records.flatMap(item => item.gender === "BOYS" ? item : []);
const withFilter = records.filter(({ gender }) => gender === "BOYS");
console.log(withReduce);
console.log(withFlatMap);
console.log(withFilter);.as-console-wrapper { max-height: 100% !important; top: 0 }
