Use module.exports instead of exports. exports is an alias to
module.exports.But if you do this:
module.exports = { a: 'a', b: 'b" };
Then it breaks the link and exports will no longer work.
As Dave mentioned JavaScript is dynamically typed. If you want to be sure about
the types in JavaScript then there's a couple approaches.
You could use TypeScript, which is a Microsoft language that gives you classes,
types, etc and then transpiles down to JavaScript.
You can also do things like:function my_function(createdOn) { if (!(createdOn
instanceof Date)) throw 'Bad';
}
To check the arguments as they come in when needed.

For making modules, there's a description of this at the Global-Object.require
page (http://docs.marklogic.com/Global-Object.require). Example:
lib.sjs:
var PI = Math.PI;
exports.area = function area(r) {
return PI * r * r;
};
Test.js:
var circle = require("lib");
circle.area(2);
Key point is to set up the exports global with references to functions you want
to export. You can then access these by requiring them in another file.
For specifying datatypes in function arguments and returns, the JavaScript
language doesn't support this.
For functions where this is particularly important, consider leaving that code
in XQuery and using it in JavaScript. You can call XQuery from JavaScript and
JavaScript from XQuery.

Subject: [MarkLogic Dev General] Javascript coding help on ML 8
Hi all
We have upgraded from ML 7 to 8 and want to replace the existing xqy code with
javascript. But I am facing the following problems :
1) How to make modules in JS
2) Specifying datatype in function arguments and return type.
Any help is much appreciated!
Thanks
Shruti Kapoor
