 The `console.info()` function is an alias for [`console.log()`][].

+<!-- YAML
+added: REPLACEME
+-->
+* `value` {any}
+* `replacer` {Function|Array|null}
+* `space` {number|string}
+
+Prints `JSON.stringify(value, replacer, space)` to `stdout`. Arguments are
+passed directly to [`JSON.stringify()`][]. This is useful for inspecting
+objects without the annotations added by [`util.inspect()`][] (such as
+`[Object: null prototype]`).
+
+```js
+console.json({ foo: 'bar' });
+// Prints: {"foo":"bar"}
+
+console.json({ foo: 'bar' }, null, 2);
+// Prints:
+// {
+//   "foo": "bar"
+// }
+
+// Works cleanly with null-prototype objects
+const obj = Object.assign(Object.create(null), { foo: 'bar' });
+console.json(obj);
+// Prints: {"foo":"bar"}
+```
+
+Throws `TypeError` for non-serializable values such as circular references.
+Use [`console.log()`][] or [`console.dir()`][] for values that may not be
+JSON-serializable.
