Code editing improvements
Great code editing ergonomics are near and dear to our hearts at Retool. We’ve recently added a few improvements that make writing JavaScript in Retool just a little bit smoother.
Inline code evaluation previews now display the type of the returned value. This is handy for quick reference when working with properties that can accept multiple types:
Retool now also supports and correctly lints ES2020 features, like the nullish coalescing operator and optional chaining. You can replace clunky expressions like {{ (localStorage.values||{}).userStatus ? localStorage.values.userStatus : 'Unavailable' }} with a simple {{ localStorage.values.userStatus ?? 'Unavailable' }}.
Lastly, we’ve improved Retool’s autocomplete to properly infer JavaScript types and offer the available methods and properties, even when chained. If using inline JSDoc comments, the defined parameters will also show up the autocomplete menus.
