fast-json-stable-stringify 2.1.0

Fast-json-stable-stringify is a deterministic JSON.stringify(), specifically a quicker version of Substack's json-stable-stringify without jsonify. This NPM package enables developers to convert a JavaScript object into a JSON string in a reliable and consistent manner, without changes in the property order impacting the resulting JSON string. It's faster and efficient, making it a preferred choice for sizable JavaScript objects. It's versatile functionality allows for a custom comparison function to be passed in as well, providing developers with more control over the stringification process.

To use fast-json-stable-stringify, you'll first need to install it via NPM using the command npm install fast-json-stable-stringify. After installation, use the require function to make it available in your file. Use the following code as an example:

var stringify = require('fast-json-stable-stringify');
var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
console.log(stringify(obj)); // Will output: {"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}

You can also provide custom comparison functions to determine the order of properties:

var stringify = require('fast-json-stable-stringify');

var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
var s = stringify(obj, function (a, b) {
    return a.key < b.key ? 1 : -1;
});
console.log(s); // Results in: {"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}

Objects with circular references can also be handled by setting opts.cycles to true.
