Leaving aside the big front end, what are the advantages of node as a language?

it has been two years since we contacted the front-end. The emergence of nodejs has made a revolutionary contribution to the front-end engineering, which also makes a large number of front-end er embrace node, and promote each other and prosper together.
but I personally have some doubts in the course of my work (some brains):

  1. if node is not implemented in js, other features (such as non-blocking asynchronous io, single thread) exist and will be used to build a front-end engineering system;
  2. With the emergence of
  3. Es6 and ts, js gradually has some industrial language properties, but at present, the mainstream is still used for middleware development. What enhancements do node have to do in the future before it has a chance to become an industrial language?

1. Not necessarily
nodejs is written in js, js is weakly typed and easy to write; for the front end, there is no or less language learning cost, which makes it easier to promote and use, so there will be more front-end engineering.

2. For example: floating point calculation. Industry requires precision.
