pull-toolkit

A tiny, dependency-free collection of everyday JavaScript utility functions — the kind of small helpers every project ends up writing at some point.

const { capitalize, slugify, unique, sum, chunk } = require('pull-toolkit');

capitalize('hello world'); // "Hello world"
slugify('Hello, World!');  // "hello-world"
unique([1, 2, 2, 3]);      // [1, 2, 3]
sum([1, 2, 3, 4]);         // 10
chunk([1, 2, 3, 4, 5], 2); // [[1, 2], [3, 4], [5]]

Why this exists

pull-toolkit is intentionally small. There's no build step, no dependencies, and no framework to learn — just plain JavaScript functions and tests, so the codebase stays easy to read from top to bottom.

This also makes it a good place to make your first open source contribution. It's the official practice repository for Pull's First Contribution program — real issues, a real review process, a real merged pull request, on a codebase small enough to hold in your head.

Installation

git clone https://github.com/pull-dev/pull-first-contribution.git
cd pull-first-contribution
npm install

There are no runtime dependencies, so npm install just sets up dev tooling.

Running tests

npm test

API

Strings

• capitalize(str) — uppercases the first letter of a string.
• slugify(str) — converts a string into a URL-friendly slug.

Arrays

• unique(arr) — returns a new array with duplicate values removed.
• sum(arr) — returns the sum of all numbers in an array.
• chunk(arr, size) — splits an array into chunks of the given size.
