So, let's get started: some() every() reduce() map() flat() filter() forEach() findIndex() find() sort() concat() fill() includes() reverse() flatMap() This list is ...
Java has had a standard interface for implementing iterators since its early days, and since Java 5, the "foreach" construction makes it easy to loop over objects that provide the java.lang.Iterable interface. (The Java collections framework and other collections frameworks, typically provide iterators for all collections.)

When x is an array, it acts like a foreach loop. {{ #x }} Some text {{ /x }} The special variable {{.}} refers to the current item when looping through an array, or the item checked in a conditional.
Originally, Rhino compiled all JavaScript code to Java bytecode in generated Java class files. This produced the best performance, often beating the C++ implementation of JavaScript run with just-in-time compilation (JIT), but suffered from two faults. First, compiling time was long since generating bytecode and loading the generated classes ...
