The documentation says you can also use an object as a configuration for prop mode. When I use the example ( {name: "javascript", json: true}) it says name.toLowerCase is not a function. Is this a bug regarding this package?

/** string|object. The mode to use. When not given, this will default to the first mode that was loaded.
It may be a string, which either simply names the mode or is a MIME type associated with the mode.
Alternatively, it may be an object containing configuration options for the mode,
with a name property that names the mode (for example {name: "javascript", json: true}). */
mode?: any;
