you also made the common error any developer make
(I am ignoring you have missed the "return" keyword)
If people at es-discuss can make error,
how can you expect an average IT developer get it right.

test this

s="fddfd(ghgg"
new RegExp('^'+s, 'i')

Error!!!

i agree, that is why I mentioned to add matchCase parameter.
or have startsWithI, containsI, endsWithI instead

Again you are missing the point that the first parameter of "replace"
at many times have to be a variable with a value which was taken from
user input.


We you cant agree on replaceAll can we atleast bring mozilla
non-standard flags parameter for String.replace as standard.
https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/replace#Syntax

You can see a lot of people asking for "replace all occurrences"
