Standard JavaScript Syntax

Standard JavaScript Syntax

The JavaScript processor supports standard JavaScript expressions containing the following features.
  • The unary and binary operators:
    () + - * / % == != < <= > >= && ||
  • The ternary
    ?:
    operator.
  • The following methods:
    charAt indexOf lastIndexOf length join substring toString
    If you apply these methods to a literal having a simple data type, you must enclose the literal in parentheses, for example:
    123.toString(); //Wrong (123).toString(); //Right "Hello, World".substring(3,7); //Wrong ("Hello, World").substring(3,7); //Right
  • The following functions:
    Math.ceil Math.floor Math.max Math.min Math.pow Math.sqrt parseFloat parseInt
The JavaScript processor does not support features such as the following:
  • The unary and binary operators:
    ++ -- typeof void >> >>> << === !== ~ & | ^
  • Assignment operators:
    = += -= *= /= >>= >>>= <<= &= |= ^=
  • The comma operator
    (,).
  • The values
    NaN
    ,
    null
    ,
    infinity
    , or
    -0
    (negative 0).
  • Data types other than string, number, and boolean.
  • The
    Date
    object.
  • The
    equalsIgnoreCase
    function.
