    Solution for outputting array of firstnames less than age of 30, only using reduce

    Asynchronous Javascript 1,051 Comments1 Min ReadAnush NarayananBy

    Hi, this is the solution for the homework question asked that is using only reduce to give the o/p of the first names of the people whose age is. < 30:

    const arr = [
{ firstname: "Akshay", age: 26 },
{ firstname: "Donald", age: 56 },
{ firstname: "deepika", age: 26 },
];
const op = arr.reduce(function (acc, curr) {
if (curr.age < 30) {
acc.push(curr.firstname);
}
return acc;
}, []); 
// we pass empty array as the inital value as accumulator and then push the 
firstnames whose age < 30

console.log(op);

    Thanks,
    Anush.
