Sum of many keys (value) of many objects in an array with different data types

Question

const products = [
{ product: 'banana', price: 3 },
{ product: 'mango', price: 6 },
{ product: 'potato', price: ' ' },
{ product: 'avocado', price: 8 },
{ product: 'coffee', price: 10 },
{ product: 'tea', price: '' },
]

Question: Find the sum of price of products using only reduce reduce(callback))?

This is my code:

const sumPrice = products.reduce(function(total, childObjectValue){
   if (childObjectValue.price != '' || childObjectValue.price != ' '){
    return total + childObjectValue.price
   } 
},0)

result ouput: 9 810

Help me resolve this problem, using only reduce() method !

you can do this

const products = [
{ product: 'banana', price: 3 },
{ product: 'mango', price: 6 },
{ product: 'potato', price: ' ' },
{ product: 'avocado', price: 8 },
{ product: 'coffee', price: 10 },
{ product: 'tea', price: '' },
]

const total = products.reduce((res, {price}) => res + (parseInt(price) || 0), 0)

console.log(total)
