I have been learning Javascript for a few weeks now(mostly just arrays, functions, for loops and if statements). I have come across a problem that has stumped me and would greatly appreciate any kind of insight or breakdown of the problem.
Here is the problem:
Create a function findItems that
• takes in two arguments: an array of items, and a type of item as a string
• returns an array of items that have a type that matches the type passed in
Using the example data below, findItems(items, "book") /* =>
[{
itemName: "Effective Programming Habits",
type: "book",
price: 18.99
}]
*/
Note: after you write this function and the first set of tests pass, a second set of tests will show up for part 2. Part 2 - Find Items, Extended
Add the following features to your findItems function:
• If there are no items in the cart array, return the string "Your cart does not have any items in it."
• If there are no items that match the given type, return the string "No items found of that type. Please search for a different item.".
Sample Shopping Cart Data
let items = [
{
itemName: "Effective Programming Habits",
type: "book",
price: 18.99
},
{
itemName: "Creation 3005",
type: "computer",
price: 399.99
},
{
itemName: "Orangebook Pro",
type: "computer",
price: 899.99
}
];
Would anyone know how to solve this? Or be able to offer a breakdown of it?
You should loop over the given array, then add any objects with the type field to a temporary array, then return the array. Something like this:
function findItems(arr, type) {
let temp = [];
for (let i = 0; i < arr.length; i++) {
const item = arr[i];
if (item.type === type) {
temp.push(item);
}
}
return temp;
}
