> But I can run node main.js? Yeah, and then what happens if you want to use modern syntax like esmodule, or maybe you want to use types with typescript? You are going to have to use npm

No, you do not. You can just use .mjs extensions for esm. You can also run typescript to transpile your code and then run it with node. You can even use loaders, etc.

Saying you are going to have to use the included package manager in node is probably the weakest argument for using go over node.

Can you run some language superset over go magically without some transpilation? No, you cannot.

You cannot build a argument comparing js to ts vs go, it doesn't follow.
