What do "module.exports" and "exports.methods" mean in NodeJS / Express

Comment

// foo.js
var exports = {}; // creates a new local variable called exports, and conflicts with

// living on module.exports
exports = {}; // does the same as above
module.exports = {}; // just works because its the "correct" exports

// bar.js
exports.foo = 42; // this does not create a new exports variable so it just works

exports in node js

Comment

require function returns exports of the require module.
module.exports is the returned object.
1)use module.exports to export single varibale e.g one class or one function 
e.g module.exports= Calculator.
2)use exports to export multiple named variables 
export.add = (a,b)=> a+b;
export.multiple=(a,b)=> a*b;
