NoScript lets you whitelist sites. Chrome's built in Javascript blocking is about as usable. Settings -> Privacy and Security -> Content Settings -> Javascript and then change "Allowed" to off. You can white list a domain by clicking on the padlock or the thing that says "Not Secure" in the URL bar on the left and clicking "Site settings" and changing Javascript to Allowed. In my opinion, the only real effect JS blocking has is you start complaining in HN comments about sites not working.
