Using Javascript is getting a bit better thanks to the latest ECMA spec. We finally have a universal module system which is designed to work both on the server and on the client.A package manager that takes advantage of ES modules is needed though, so not NPM. Second, static analysis tools like Typescript compiler or Flow can help greatly with typing with little setup or configuration needed. For instance I use Typescript compiler with js files directly in VSCode. Finally linters can help avoid common mistakes. The experience is certainly better than 10 years ago thanks to all the new tools and specs at the developer's disposal.
