    We're excited to hear what you think of this idea! We're hoping that this proposal can make coding easier for TypeScript and JavaScript users at every scale.

    The Types as Comments proposal means that browsers could run TypeScript-checked code directly, (even though they wouldn't do any type-checking). That means faster iteration with all the type-checking and editing experience you know and love today.
