8,241 Points.join() isn't working
when i run the program using node gets me an error and pint to the dot between the array and 'join()' method. Here is my code
var products = [
{ name : 'pc', inventory : 5, unit_price : 45.99 },
{ name : 'iPhone', inventory : 7, unit_price : 40.99 },
{ name : 'iPad', inventory : 10, unit_price : 35.99 }
];
function listProducts(products_arr) {
var productsNames = [];
for ( var i = 0; i < products_arr.length; i++ ) {
productsNames += products_arr[i].name;
}
return productsNames.join();
}
console.log(listProducts(products));

And then "join" is not a valid method for a string.

8,241 PointsYeah, I figured that out. If you see my comment on my question.Sometimes I forget some really basic stuff...;(

I had no idea that combining a list with a string would produce a string — but now I do.

8,241 PointsNevermind figured it out after watching the solution.Forgot that to add value(s) to an array you use 'push()' method.
