array-extensions

A set of extensions to the array object to make dealing with them easier, neither unique or new, and with lots of inspiration from other languages, stackoverflow and other github projects :)

Includes TypeScript definition files.

Usage:

(Also see tests for more usage patterns)

import "array-extensions";

// async/await
await [1,2,3].forEachAsync(async (item) => {
    // do something await/async with {item}
})

// then/cath/finally
[4,5,6].forEachAsync(async (item) => {
    // do something async with {item}
}).then(() => {
    // execute something when done 
})

Available functions

// proper sequential forEach on async functions
Array<T>.forEachAsync(async callback): Promise<void>

//Concurrent async forEach, with threadCount
Array<T>.forEachAsyncConcurrent(async callback: (item: T) => void, threadCount = 4, continueOnError = true): Promise<void>

// proper sequential map on async functions
Array<T>.mapAsync<TT>(async callback: (item: T) => TT): Promise<TT>

// Concurrent async map, with threadCount
Array<T>.mapAsyncConcurrent<TT>(async callback: (item: T) => TT, threadCount = 4, continueOnError = true): Promise<TT>

// simple reduce groupby, 
Array<T>.groupBy(propName: string)
Array<T>.groupBy(callback: (item: T) => string)

// Following function should say it all, will add more over time (Only works on number arrays)
Array<T>.max(callback: (item: T): number): number
Array<T>.min(callback: (item: T): number): number
Array<T>.sum(callback: (item: T): number): number
