Question

I would like to filter out the array of objects by their price. Ex: If price = 1.00 then it should return the index of that object in the array (index 1 and 3 given code below). *using only javascript

var items = [ { name: 'toy1', price: '12.00', quantity: 12 } , { name: 'toy2', price: '1.00', quantity: 5 } , { name: 'toy3', price: '11.00', quantity: 2 } , { name: 'toy4', price: '1.00', quantity: 2 } ]

Answer 1

function filter(items, price){
    var result = {};
    var k = 0;
    for(var i = 0;i<items.length;i++){
        if(items[i]["price"]==price){
            result[k++] = i;
        }
    }
    return result;
}

// making function call
var items = [ { name: 'toy1', price: '12.00', quantity: 12 } , { name: 'toy2', price: '1.00', quantity: 5 } , { name: 'toy3', price: '11.00', quantity: 2 } , { name: 'toy4', price: '1.00', quantity: 2 } ]
console.log(filter(items,1.00));
