There is a way to serialize a function in JS, but you'll have to eval it on the other side and it will also lose access to it's original scope. A way to do it would be:

JSON.stringify(objWithFunction, function(key, val) {
  if (typeof val === 'function') {
    return val + ''; // implicitly `toString` it
  }
  return val;
});

There are some legitimate uses for what you're asking despite what people are posting here, however, it all depends on what you're going to be using this for. There may be a better way of going about whatever it is you're trying to do.

typescript-json, 2x faster JSON stringify with only one line

TSON.stringify(numArr) Is roughly 10x slower on an array of 1m numbers. Replacing it with strings and it is 2x slower. Ironically, replacing it with TSON.stringify(..) is then comparable. Edit: // type.ts import TSON from 'typescript-json'; let numInArray = 1000000; let a: number[] = []; for (let i = 0; i < numInArray; i++) { a.push(i); } let b = { item: a }; let iterations = 10; let ms = Date.now() for (let i = 0; i < iterations; i++) { TSON.stringify<{item: number[]}>(b); } let tsonDur = Date.now() - ms; ms = Date.now(); for ( let i = 0; i < iterations; i++) { JSON.stringify(b); } let jsonDur = Date.now() - ms; console.log('tson: ', tsonDur); console.log('json: ', jsonDur); Running in the latest node:16 docker image // output root@5734a17bed1e:~/tester# npx ttsc type.ts && node type.js tson: 2352 json: 254 More on reddit.com
