“Each CSP directive lets you indicate which origins are trusted by using a whitelist-based approach. User agents which support CSP will avoid fetching resources that don’t match your server’s CSP directives. This means our server can determine, at a granular level, which origins are allowed for which kinds of resources.”

“In asynchronous code flows, it is commonplace to execute two or more tasks concurrently. While Async Functions make it easier to write asynchronous code, they also lend themselves to code that is serial. That is to say: code that executes one operation at a time. A function with multiple await expressions in it will be suspended once at a time on each await expression until that Promise is settled, before unsuspending execution and moving onto the next await expression – not unlike the case we observe with generators and yield.”
