"print" in Eloquent JavaScript by MARIGNE HAVERBECK?

Question

JavaScript

1. How is it implemented?
2. To what extent is this methodologically correct? "print" on the client seems to cause printing to the printer.

Examples can be seen here eloquentjavascript.net/chapter3.html

Answer 1

Implemented like this:

  win.print = function() {
    var accum = [];
    for (var i = 0; i != arguments.length; i++)
      accum.push(String(arguments[i]));
    var joined = accum.join("");
    env.output(DIV(null, preNewline != "\n" ? joined.replace(/\n/g, preNewline) : joined));
  };

That is simply redefined.
In my opinion, when learning a language, it is quite logical and customary to name the function that prints in its console with the name print. JavaScript is not only used in browsers.
