Steps to reproduce

When executing code containing the String.prototype.replaceAll method, a TypeError: Object doesn't support property or method 'replaceAll' occurs.

Proof of concept

var replaceWith = function (inputStr) {
    return inputStr.replaceAll('a', 'b');
};
var originalStr = 'Y)a,K;aC&.';
var modifiedStr = replaceWith(originalStr);
print(modifiedStr);

Exception or Error

TypeError: Object doesn't support property or method 'replaceAll'
   at replaceWith (/home/test.js:2:5)
   at Global code (/home/test.js:5:1)

@ayuan0828 , works perfectly fine when I use the same code in console. Please attach a screenshot on when you are facing the issues.

Here's a screenshot of my execution, and I'm very confused.

@ayuan0828 then its might be that originalStr is not a string but an object which is getting sent.

The function "matchAll" is the same case, maybe for the same reason?
