Wish you had some immutability in Javascript? Now you can!

var t = {a: 1, b: 2}.immutable();
console.log(t.a, t.b);
try {
  t.a = 3; // ->  Uncaught Error: a is immutable and cannot be modified.
} catch (e) {
  console.log(e);
}

var t2 = t.copy({a: 3});

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
