isJSON doesn't validate json-encoded strings

[alust]

> import {Validator} from "class-validator";
{}
> const validator = new Validator();
undefined
> let json_str = JSON.stringify('abc');
undefined
> validator.isJSON(json_str);
false

However json-encoded objects and arrays are validated correctly:

> json_str = JSON.stringify({});
'{}'
> validator.isJSON(json_str);
true
> json_str = JSON.stringify([]);
'[]'
> validator.isJSON(json_str);
true

Is string really valid JSON?

Any update on this?

@vlapo yes it is, the JSON specification states that a string is a valid Json
