Usage
import { serialize } from 'seroval';
const object = {
number: [Math.random(), -0, NaN, Infinity, -Infinity],
string: ['hello world', '<script>Hello World</script>'],
boolean: [true, false],
null: null,
undefined: undefined,
bigint: 9007199254740991n,
array: [,,,], // holes
regexp: /[a-z0-9]+/i,
date: new Date(),
map: new Map([['hello', 'world']]),
set: new Set(['hello', 'world']),
};
// self cyclic references
// recursive objects
object.self = object;
// recursive arrays
object.array.push(object.array);
// recursive maps
object.map.set('self', object.map);
// recursive sets
object.set.add(object.set);
// mutual cyclic references
object.array.push(object.map);
object.map.set('mutual', object.set);
object.set.add(object.array);
const result = serialize(object);
console.log(result);
