Hi Don! A SKU (short for Stock Keeping Unit), is a unique identifier for a product. There's a pretty good Wikipedia article that goes into more detail, but the general idea is that it identifies what product someone's talking about uniquely, so that there can't be any confusion.

In that video, Randy starts with an array of products, identified with the SKU as the key. But, he wants to add the SKU to the information for each product as well, to make sure that when iterating through the array he can easily access what the SKU is. The code you included with your question is how we do that. We loop over each item in the products array, and set the "sku" value for each object to equal the key for the array element.

I hope that helps! Definitely feel free to ask any followup questions you have if you need more info!
