Ts-array-ext NPM

npm.io

TS-Array-Ext is a minimalist TypeScript library that provides a few utility functions to the Array prototype class. Inspired by LINQ functionality we aim to bring a few easy to use functions that we keep rewriting over and over. No longer. It is time to extend base JavaScript Array functions.

🧠 Familiar LINQ operations & patterns
💪 Strongly typed
🔥 Chainable
📦 <2kB mini library
👫 Individual imports for optimization
💯 100% coverage. No less.

Getting started

Installation

npm i ts-array-ext --save

Then either import the entire lib:

import "ts-array-ext";

Or the individual functions.

import "ts-array-ext/min";
import "ts-array-ext/sum";

Your arrays will have the functions.

const totalScore = myArr.sum(x => x.score);
