Is there a JS function that will turn [/a/, []] into "[/a/, []]"? JSON.stringify mangles regexes and toString() mangles arrays. > JSON.stringify([/a/, []]) '[{},[]]' > [/a/, []].toString() '/a/,'

Nothing built-in. The closest is to use the map function on JSON.stringify and convert them to strings: JSON.stringify(VALUE, (key, value) => { if (value instanceof RegExp) { return `/${value.source}/${value.flags}`; } else { return value; } });

If you're using Node and are just using it for debug purposes then you can also use `require('util').inspect`.

Inspect's whitespace handling is a problem for esoteric reasons, but it's good to know about both of these options for the future; thanks!

For more info, see MDN for the `replacer` function: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Example_replacer_as_a_function …
