A listing of the Array functions are given below:
 +
 +
Every Array Member Function is also globalized with the same name but with Uppercase First Letter. For example, .chunks has a twin Global called Chunks, which take first parameter as an array, and followed with the exact same parameters of the original member function. Hence Chunks(Array,ChunkSize) will work the same. If there is an existing function with a similar name, then the globalized name will have a $x appended to it. For example, .map is also available as Map$x.

Array.R = Array.reduce

Array.M = Array.map

Array.F = Array.filter

==Combinator Functions==

Array.$fns takes an array of functions and creates combinator pipe.
 +
 +
Array.$combinators takes take the name of a combinator and generate a function with that combinator behavior. These are globalized with λ prefix. For example, B Combinator is λB in global space.

ARRAY FUNCTIONS

A listing of the Array functions are given below:

Every Array Member Function is also globalized with the same name but with Uppercase First Letter. For example, .chunks has a twin Global called Chunks, which take first parameter as an array, and followed with the exact same parameters of the original member function. Hence Chunks(Array,ChunkSize) will work the same. If there is an existing function with a similar name, then the globalized name will have a $x appended to it. For example, .map is also available as Map$x.

Quick Reference: Array.R = Array.reduce Array.M = Array.map Array.F = Array.filter


Function name Parameter

Function Name Parameters Notes
$ Function/Array of Functions Apply functions to each element of array
$$ Function/Array of Functions Apply functions to each row of array
$$$ Function/Array of Functions Apply functions to each column of array
$$F Function/Array of Functions Append results of functions to each row
$A Parameter Get attributes from an array of objects
$C Column Array to apply, Function/Array of Functions, Optional Parameters Apply a function with parameters to a column
$CELLS Row/Column Area indices and width and height to apply (l,t,w,h), Function/Array of Functions, Optional Parameters Apply a function with parameters to a cell area
$d Same as Array.$diag
$diag Apply function to the proper diagonal of an array
$dth Apply function to dth diagonal of an array
diagonal Get the nth diagonal of an array
$R Row Array to apply, Function/Array of Functions, Optional Parameters Apply a function with parameters to a row
$X SomeArray Combines two arrays using an across operation. Reverse is .X$
$x SomeArray Same as $X
$_ Mode, Functions, Parameters Apply a function to the entire array as one aggregate call
__$ Mode, Functions, Parameters Using a mode (value, valuebyrow, index etc), apply a function to the cells with parameters

Combinator Functions

Array.$fns takes an array of functions and creates combinator pipe.

Array.$combinators takes take the name of a combinator and generate a function with that combinator behavior. These are globalized with λ prefix. For example, B Combinator is λB in global space.
