JavaScript can allow e-commerce sites to dynamically update products on their category pages. This makes sense since their inventory is in a constant state of flux due to sales. However, if Google doesn't execute your JS files, will it actually be able to "see" your content?
For an e-commerce site that relies on online conversions, not having its products indexed by Google can be disastrous.
