}

I need to display the results of a returned JSON object using Angular 2. I am trying to use Lodash to filter out the unrequired key-value pairs.

I have filtered out the values using:

      products.data.forEach(element => {
        var prodr = _.pick(products.data, ['0.name', '0.sku', '0.description', '0.price.0.amount']);
        console.log(prodr);
    });

This code loops through the objects but returns objects of the same value because I have set them to "0". I think I need to set them to "i" and add in a for function, but I am quite new to javascript and typescript and I can't get the syntax right.

When you are using forEach as per your sample data, the below code should work

 products.data.forEach(element => {
    let product = {
                name : element.name, 
                sku : element.sku, 
                description : element.description,
                price: element.price[0].amount
                }
    console.log(product);

});
