  • R gsub. gsub() function replaces all matches of a string, if the parameter is a string vector, returns a string vector of the same length and with the same attributes (after possible coercion to character).
  • let firstName = 'John' ; let fullName = firstName.concat ( ' ', 'Doe' ); console .log (fullName); // "John Doe" console .log (firstName); // "John". The concat () method concatenates one or more strings to another and returns the result string. Note that the concat () method does not modify the original string.
  • Regular expression support has been in the standard Java runtime for ages and is well integrated (e.g., there are regex methods in the standard class java.lang.String and in the “new I/O” package). There are a few other regex packages for Java, and you may occasionally meet code using them, but pretty well all code from this century can be ...
