return array of objects

Question

I have the solution but Is there any other nicer way to do in javascript or is it possible to modify the arr1 itself and have arr1 as array of objects alone

I have array of objects and string

arr1 = [{
    id: 'id1',
    name: 'name1'
}, {
    id: 'id2',
    name: 'name2'
}, '/roll', '/roll1'];

i would like to have array of objects alone at the end

newarr1 = [{
    id: "id1",
    name: "name1"
}, {
    id: "id2",
    name: "name2"
}]

current solution

arr1.map((item) => {
    if (typeof item === 'object') return newarr1.push(item)
})

Never use map where you need a forEach. let newArr1 = []; arr1.forEach((item) => { if (typeof item === 'object') newarr1.push(item); }); — mplungjan

newArr = arr1.filter(item => typeof item === 'object')

Nice answer:) This is not needed for OP's case, but a good-to-know: arrays are considered objects too, and if OP has nested arrays and wants to include/exclude them, an additional check for Array.isArray(item) is going to help :)

const isObject = item => Object.getPrototypeOf(item) === Object.prototype;

const newarr1 = arr1.filter(isObject);

Demo

const isObject = item => Object.getPrototypeOf(item) === Object.prototype;

const arr1 = [{id: 'id1', name: 'name1'}, {id: 'id2', name: 'name2'}, '/roll', '/roll1'];
const newarr1 = arr1.filter(isObject);

console.log(newarr1);
