Shopify – Check if an element exists of another array of objects

I have the two following Arrays of objects.

const respProducts = [
    {
        "cursor": "eyJsYXN0X2lkIjo4OT234234sYXN0X3ZhbHVlIjo4OTkzOTgyMjExfQ==",
        "node": {
            "id": "gid://shopify/Product/8923422211",
            "title": "California Here"
        }
    },
    {
        "cursor": "eyJsYXN0X2lkIjo5234234sYXN0X3ZhbHVlIjo5MDExNDM0MzA3fQ==",
        "node": {
            "id": "gid://shopify/Product/923423434307",
            "title": "Texas 2000 Here"
        }
    },
    {
        "cursor": "eyJsYXN0X2lkIj234234LCJsYXN0X3ZhbHVlIjo5MzM4MDczODcwfQ==",
        "node": {
            "id": "gid://shopify/Product/23423470",
            "title": "Texas Black Here"
        }
    }
]

const currentTemplates = {
    "Texas 2000 Here": {
        "productTemplate": {
        },
        "colorVariants": false
    },
    "Alabama": {
        "productTemplate": {
        },
        "colorVariants": false
    },
    "Alaska": {
        "productTemplate": {
        },
        "colorVariants": false
    },
    "Arizona": {
        "productTemplate": {
        },
        "colorVariants": false
    }
}

I need to check if an item from respProducts is found in currentTemplates if so do not return it if it is found then return it. I need respProducts to retain it’s structure.
Only remove any items that are in currentTemplates.

My attempt:

const respBuildArray = respProducts.filter(el => el.node.title.includes(Object.keys(currentTemplates).map(el => el)));

In the above example I would like to get back:

const respBuildArray = [
    {
        "cursor": "eyJsYXN0X2lkIjo4OT234234sYXN0X3ZhbHVlIjo4OTkzOTgyMjExfQ==",
        "node": {
            "id": "gid://shopify/Product/8923422211",
            "title": "California Here"
        }
    },
    {
        "cursor": "eyJsYXN0X2lkIj234234LCJsYXN0X3ZhbHVlIjo5MzM4MDczODcwfQ==",
        "node": {
            "id": "gid://shopify/Product/23423470",
            "title": "Texas Black Here"
        }
    }
]

since Texas 2000 Here is in currentTemplates.
My above code returns an empty array.

    There is no need for the map(). And it seems like you want to negate (!) the includes()

    const respProducts = [{"cursor": "eyJsYXN0X2lkIjo4OT234234sYXN0X3ZhbHVlIjo4OTkzOTgyMjExfQ==", "node": {"id": "gid://shopify/Product/8923422211", "title": "California Here"} }, {"cursor": "eyJsYXN0X2lkIjo5234234sYXN0X3ZhbHVlIjo5MDExNDM0MzA3fQ==", "node": {"id": "gid://shopify/Product/923423434307", "title": "Texas 2000 Here"} }, {"cursor": "eyJsYXN0X2lkIj234234LCJsYXN0X3ZhbHVlIjo5MzM4MDczODcwfQ==", "node": {"id": "gid://shopify/Product/23423470", "title": "Texas Black Here"} } ]
const currentTemplates = {"Texas 2000 Here": {"productTemplate": {}, "colorVariants": false }, "Alabama": {"productTemplate": {}, "colorVariants": false }, "Alaska": {"productTemplate": {}, "colorVariants": false }, "Arizona": {"productTemplate": {}, "colorVariants": false } } 

const allTemplateTitles = Object.keys(currentTemplates);

const filtered = respProducts.filter(e => !allTemplateTitles.includes(e.node.title))

console.log(filtered)

    You can use the in operator to check if the string exists as a property name (key) in currentTemplates and use that as criteria for filtering. This avoids creating an unneeded array of keys:

    const respProducts = [{"cursor":"eyJsYXN0X2lkIjo4OT234234sYXN0X3ZhbHVlIjo4OTkzOTgyMjExfQ==","node":{"id":"gid://shopify/Product/8923422211","title":"California Here"}},{"cursor":"eyJsYXN0X2lkIjo5234234sYXN0X3ZhbHVlIjo5MDExNDM0MzA3fQ==","node":{"id":"gid://shopify/Product/923423434307","title":"Texas 2000 Here"}},{"cursor":"eyJsYXN0X2lkIj234234LCJsYXN0X3ZhbHVlIjo5MzM4MDczODcwfQ==","node":{"id":"gid://shopify/Product/23423470","title":"Texas Black Here"}}];
const currentTemplates = {"Texas 2000 Here":{"productTemplate":{},"colorVariants":false},"Alabama":{"productTemplate":{},"colorVariants":false},"Alaska":{"productTemplate":{},"colorVariants":false},"Arizona":{"productTemplate":{},"colorVariants":false}};
const expected = [{"cursor":"eyJsYXN0X2lkIjo4OT234234sYXN0X3ZhbHVlIjo4OTkzOTgyMjExfQ==","node":{"id":"gid://shopify/Product/8923422211","title":"California Here"}},{"cursor":"eyJsYXN0X2lkIj234234LCJsYXN0X3ZhbHVlIjo5MzM4MDczODcwfQ==","node":{"id":"gid://shopify/Product/23423470","title":"Texas Black Here"}}];

const actual = respProducts.filter(
  (p) => !(p.node.title in currentTemplates),
);

console.log(JSON.stringify(actual) === JSON.stringify(expected)); // true
console.log(actual);
