Conversion of JavaScript's Array methods to AutoHotkey

AutoHotkey lacks built-in iteration helper methods to perform many of the common array behaviors found in other languages. This package ports most of JavaScript's Array object methods to AutoHotkey's Array object. Because Javascript is zero-based and AutoHotkey is not, there are some slight differences.

Ported Methods

• concat
• every
• fill
• filter
• find
• findIndex
• forEach
• includes
• indexOf
• join
• lastIndexOf
• map
• reduce
• reduceRight
• reverse
• shift
• slice
• some
• sort
• splice
• toString
• unshift
• values

Installation

In a terminal or command line navigated to your project folder:

npm install array.ahk

You may also review or copy the library from ./export.ahk on GitHub

In your code only export.ahk needs to be included:

#Include %A_ScriptDir%\node_modules
#Include array.ahk\export.ahk

msgbox, % [1,2,3].join()
; => "1,2,3"

You may also review or copy the library from ./export.ahk on GitHub; #Incude as you would normally when manually downloading.

API

The package modifies the Array object when #Included near the top of your script.

Array.<fn>([params*])

; Map to doubled value
arrayInt := [1, 5, 10]
arrayInt.map(func("fn_doubleInt"))
; => [2, 10, 20]

fn_doubleInt(int) {
	return int * 2
}


; Map to object property
arrayObj := [{"name": "bob", "age": 22}, {"name": "tom", "age": 51}]
arrayObj.map(func("fn_returnName"))
; => ["bob", "tom"]

fn_returnName(obj) {
	return obj.name
}


; Method chaining
arrayObj := [{"name": "bob", "age": 22}, {"name": "tom", "age": 51}]
msgbox, % arrayObj.map(func("fn_returnProp").bind("age"))
	.map(func("fn_doubleInt"))
	.join(",")
; => "44,102"

fn_returnProp(prop, obj) {
	return obj[prop]
}

Sorting

JavaScript does not use start/end or left/right parameters, and this implementation follows the same approach.

array.sort([params*])

[11,9,5,10,1,6,3,4,7,8,2].sort()
; => [1,2,3,4,5,6,7,8,9,10,11]


[11,9,5,10,1,6,3,4,7,8,2].sort(func("fn_reverse"))
fn_reverse(a, b) {
	return b - a
}
; => [11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1])
