data.map is not a function

Question

I\'m bashing my head against an error I can\'t work out how to fix. I have the following;

JSON

{\"products\":
[
    {
        \"product_id\" : \"123         


        

Answer 1

If you want to map an object you can use Lodash. Just make sure it's installed via NPM or Yarn and import it.

With Lodash:

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

Answer 2

You can always do the following:

const SomeCall = request.get(res => { 

const Store = []; 
Store.push(res.data);

Store.forEach(item => { DoSomethingNeat 
});
});

Objects, {} in JavaScript does not have the method .map(). It's only for Arrays, [].

So in order for your code to work change data.map() to data.products.map() since products is an array which you can iterate upon.
