I believe these should be passed parameters which provide info about the arg and expected type as opposed to a fixed string. See invalidArgType(name, expected, actual) in internal/errors.js

Agreed.
I think invalidArgType(name, expected, actual) is unsuitable for all situations. Because "Invalid argument type" can caused by many reasons:

Argument must be one or more specified type, but recieve other.

Argument must NOT be one or more specified type, but recieve.

In some specified condition, the above two happen.

But invalidArgType(name, expected, actual) in internal/errors.js can only handle the first one, without concerning about the rest.

Should I extend the invalidArgType method in order to make it suitable for all situations?

I think this should be passed arguments that provide info about the expected argument as opposed to a specific string. Look at the function associated with ERR_INVALID_ARG_TYPE in internal/errors.js. Same comment applies to everywhere ERR_INVALID_ARG_TYPE is used.

This is probably a good candidate for adding a function that takes info about the arguments and the expected range as opposed to using a fixed string.

To avoid confusion, perhaps ERR_NO_LONGER_SUPPORTED would be better here. The method itself is not deprecated, only one particular way of calling it.

I don't know if this error code is suitable.
Should we have a new error code for it?

It should probably be a RangeError

This should be the name of the argument as opposed to 'first argument'

Sames goes for other similar instances.

What does the string end up being here ? I think this may be the first case were we have the 'not' cases versus listing out what it should be.

I extended the invalidArgType(name, expected, actual) in internal/errors.js to make it adapt to the 'not' cases. See here.

The case here will end up being:

TypeError [ERR_INVALID_ARG_TYPE]: The "value" argument must not be of type number. Received type number

The tests for it is also changed.

I think it should likely be 'string encoding'

In other places UNKNOWN_ENCODING so that should be used here as well.

but IMHO name should stay encoding like in the doc - https://nodejs.org/api/buffer.html#buffer_new_buffer_string_encoding

I think UNKNOWN_ENCODING is more suitable for this.

This does not quite fit with the new approach. It really should be one of 'a' or 'b' instead of 'arguments'. I think we may need to different cases one that throws an error for 'a' and one for 'b' to be consistent with how we through errors everywhere else. To match that the second string passed in should be the name of the argument defined in the function definition that is wrong.

IMHO it should be buf1 and buf2 alike in the API docs https://nodejs.org/api/buffer.html#buffer_class_method_buffer_compare_buf1_buf2

Could you replace .* with [^"]* just to be more explicit
(and at L65 too)

Since common is becoming a Winnebago, I'm actually not in love with these two. The old one is reused 3 times, and the new one 2 times.
Maybe for your next PR you could inline them 😉

@starkwang this is really good work. I would approve after you address the comments.

Optionally if you have some more patience to replace all the RegExps with common.expectsError that would be fantastic. But it could also wait for a future PR.
