Eachable type

Parent type of all types that have each() method

Direct children types

Eachable1: Eachable which each() calls the callback with one argument
Direct subtypes: 16

Eachable2: Eachable which each() calls the callback with two arguments
Direct subtypes: 2

all(e:Eachable, predicate:Any) Source: stdlib.ngs:1565

Check whether all elements in arr satisfy the given predicate.

e	The items to check
predicate	Test function

Bool

[1,2,3].all(X<10)   # true
[1,2,10].all(X>5)   # false

map(e:Eachable, mapper:Fun) Source: stdlib.ngs:257

Map e to an Arr (array) of values using mapper.

e	Object of any type that has each(e, callback) implemented

Arr

[1,2,3].map(X*4)  # [4,8,12]

reject(something:Eachable, predicate:Any) Source: stdlib.ngs:456

Filter something to an Arr (array) of values using predicate

something	object of any type that has each(something, callback) implemented
predicate	Decision function to be called with each item as first argument. When predicate(item) returns true, the item will not appear in the resulting array

Arr

(1...10).reject(F(num) num % 2 == 0)  # Gives [1,3,5,7,9]
(1...10).reject(X<5)  # Gives [5,6,7,8,9,10], predicate called as predicate(item, 5)
