typeof opts.masked === string, is that ok?

[dnsorlov]

Sorry if my question is stupid, but code expectedly throws error that 'string is not define' (cause 'string' should be string), what's going on?

Use String (with a capital letter)

opts.masked = typeof opts.masked === string May be 'string' must be in quotes? Now it's not.
