In programming terminology, a lambda is often defined as part of the functional language model. It is a function applied to a list or iterators to process them in some way.
In Haxe, a Lambda can often be found as part of Lists or Arrays to process, filter, or other check through some existing data structure.
In Haxe, the use of Lambda is a static extension to existing iterator functionality. Unlike the normal import keyword functionality, static extensions are included through the keyword using.
Working with Lambdas
Some common Lambda functions include has(), find(), foreach(), and filter(). These can be used to work on existing data structures to search or test its contents.
