Question 364814 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – How can I fix code for a simple array. I created a constructor by using key word:new I run code and get: ReferenceError: Products not defined

I’m working out of a text book JavaScript All-In_One. I’m following the directions to write an array. I’m using vscode. This is my array:

const list = new Products['eggs','milk','cheese','garlic','onion','kale','salt','pepper'];

When I run visual studio I get the error. Products not defined.

I tried declaring the array before assigning it. When I run the code I expect to get the list in the array. When I write Products.length I expect to get the length of the array characters. I tried using the console in the browser and I get the same error.

    If the Products constructor accepts an array argument:

    const list = new Products(['eggs','milk','cheese','garlic','onion','kale','salt','pepper']);

    The syntax for instantiating a class is:
    new <class_name>(arg1, arg2, ...);

    It looks like you were trying to do:

    const Products = new Array('eggs','milk','cheese','garlic','onion','kale','salt','pepper'); 
console.log(Products.length,Products)
// or ...
const Products2=['eggs','milk','cheese','garlic','onion','kale','salt','pepper']; 
console.log(Products2.length,Products2);
