  • This is after all in any example on node.js there is - Vyacheslav Gusser
  • what is???? how to add one written .js to another as in php function include ????? there is no such thing - shol
  • not so read the question and start to comment, there is, no, in any textbook .... - shol
  • If you expect to get the behavior exactly the same as in php, as it includes the include script in the context of the script in which the include is done, and all the global variables in the file that include'li are available in the calling script, then no, that does not work in node. LEARN DOCUMENTATION, you did not read the documentation and start asking questions - Vyacheslav Gusser
  • so I asked, maybe there are thoughts how to implement - shol

require ()

var fs = require("fs");

  • to use functions, variables, etc. you need to export them (these are the basics of node.js) - Alexandr Maliovaniy
  • read carefully my question - shol
  • I did not mean the import of modules - shol

To include scripts into each other is used

 const sum = require('./sum');

And inside sum.js, this export

 module.exports = (a, b) => a + b

Here is the documentation for the https://nodejs.org/api/modules.html modules
