Description Tomas Hurka 2015-05-28 14:12:15 UTC

string.replace(“.”,”/“) is much slower than string.replace(‘.’,’/‘). This is because String.replace method with String parameters uses regexp internally and using regexp is a huge overkill for this usecase. It would be nice to have a hint to use replace(char, char) if the replace(String, String) method replaces just one character with another one.
