[es2021] replaceAll no warning

[hothvictor]

Already updated to the latest caniuse-lite version, but still no warning message.

Are there anyone have the same issue?

Hi, yes I have the same issue, any news about it?

[mcMickJuice]

I am seeing this warning:

[tantian1498]

when I use: const statisticsStrTip = 'test'.replaceAll("", " "), it is useful；
but not useful when I use：
let statisticsStr = '-111_'
const statisticsStrTip = statisticsStr.replaceAll("_", " ")

what should I do？

@mcMickJuice "anystring".replaceAll does work, but when you replace "anystring" with anyvariable it does not.

"".replaceAll("+", "-") // error

const a = ""
a.replaceAll("+", "-") // no error

Issue seem to be here (helpers -> lintMemberExpression):

in case of "".replaceAll() it goes into if branch and gets String.replaceAll protochain.
in case of a.replaceAll() it goes to else branch and just passes through (protochain would be a.replaceAll).

From AST it doesn't know that a is a string.

Also it does flag String.replaceAll as issue (while it doesn't even exist) and doesn't flag String.prototype.replaceAll so there is no workaround afaik
