🥣 @iterable-iterator/reduce

Iterable reducers for JavaScript. See docs.

⚠️ Depending on your environment, the code may require regeneratorRuntime to be defined, for instance by importing regenerator-runtime/runtime.

import {range} from '@iterable-iterator/range';
import {reduce} from '@iterable-iterator/reduce';
import {mul, add} from '@functional-abstraction/operator';

reduce( mul , range( 2 , 6 ) , 1 ) ; // 120
reduce( add , range( 2 , 6 ) , 1 ) ; // 15

import {sum} from '@iterable-iterator/reduce';
sum( range( 6 ) ) ; // 15

import {any, all, some} from '@iterable-iterator/reduce';
any( [ false* , true , ... ] ) ; // T
any( [ false* ] ) ; // F
all( [ true* , false , ... ] ) ; // F
all( [ true* ] ) ; // T
some( [ true , true , false , true , ... ] , 3 ) ; // T
some( [ true , false , true , false* ] , 3 ) ; // F

import {increasing, decreasing} from "@total-order/primitive" ;
import {min, max} from '@iterable-iterator/reduce';
min( increasing , [ 2 , 1 , 3 ] ) ; // 1
max( increasing , [ 2 , 1 , 3 ] ) ; // 3
