In Node.js the new ECMAScript standards can be used without problems, as you don't have to wait for all your users to update their browsers - you are in charge of deciding which ECMAScript version to use by changing the Node.js version, and you can also enable specific experimental features by running Node.js with flags.

npm with its simple structure helped the ecosystem of node.js proliferate, and now the npm registry hosts almost 500,000 open source packages you can freely use.
