Identifiers

▪Identifiers are the names of functions or variables.

▪They start with a letter or an underline (_). Other letters, underlines, or numbers can follow afterwards.

▪The exception to this are all characters that do not belong to the English alphabet, e.g. 'ä' or 'é'.

▪There is no restriction for the length of an identifier.

▪Furthermore, there is a distinction between capitalized letters and the use of small letters. For example, Name and name are two different identifiers.

▪Examples for valid identifiers: textFunc, _testVar2, new, NEW, New_12340

▪Examples for invalid identifiers: 12help, 1234, grösser, straße
