How do I load a library?

Question

How do I load a library?

I feel very foolish for asking such a supposedly mundane thing, but I couldn't find the answer on Ecma-262 or MDN.

Solution must work with d8 (V8), jjs (Nashorn), js (SpiderMonkey), rhino (Rhino), seed (JavaScriptCore).

• Quentin: JavaScript has no native features for loading libraries. How you do it is host environment specific (but many support AMD).

Answer 1

if ('undefined' === typeof(require)) {
 if ('function' === typeof(load)) {
 require = load;
 } else if ('object' === typeof(imports)) {
 require = function(library_name) {
 eval(imports.gi.Gio.file_new_for_path(
 library_name).read().get_contents());
 }
 } else {
 throw('require not implemented');
 }
}
require('./some_library.js');
console.log(some_library.some_function(some_parameters));
