This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
String functions common to many languages are listed below, including the different names used. The below list of common functions aims to help programmers find the equivalent function in a language. Note, string concatenation and regular expressions are handled in separate pages. Statements in guillemets (« … ») are optional. CharAt
