Getting Started

Quick Start

Install the library using

go get github.com/rjNemo/underscore

Please check out the examples to see how to use the library.

package main

import (
	u "github.com/rjNemo/underscore"

func main() {
	numbers := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}
	// filter even numbers from the slice
	evens := u.Filter(numbers, func(n int) bool { return n%2 == 0 })
	// square every number in the slice
	squares := u.Map(evens, func(n int) int { return n * n })
	// reduce to the sum
	res := u.Reduce(squares, func(n, acc int) int { return n + acc }, 0)

	fmt.Println(res) // 120


These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.


You need at least go1.18 for development. The project is shipped with a Dockerfile based on go1.18.

If you prefer local development, navigate to the official download page and install version 1.18 or beyond.


First clone the repository

git clone https://github.com/rjNemo/underscore.git

Install dependencies

go mod download

And that’s it.


To run the unit tests, you can simply run:

make test
