How to write readmes for your projects

"Your" project is a project you happen to make any changes at. Any Readme can contain also extra parts, specific for a project.

Necessary parts

Underneath is a template you can use in a project without any (or with scaffolded) readme:

Intro

kiote

// stateful vs stateless
let x = 1;
const stateful = () => x = x + 1;
stateful(); // x = 2
stateful(); // x = 3

const stateless = (x) => x + 1;
stateless(x); // x = 4
stateless(x); // x = 4

 docker build -t run-testing20 .
 docker run -it --entrypoint /bin/sh run-testing20:latest

Tasks

Two sum

Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Example:

kiote

Play sound

aplay test.wav

Record sound

arecord -D plughw:1,0 -d 3 test.wav

Rotate screen

irb(main):001:0> def a(b = {})
irb(main):002:1> puts b[:one]
irb(main):003:1> end
=> :a
irb(main):004:0> a

=> nil
irb(main):005:0> a(nil)
NoMethodError: undefined method `[]' for nil:NilClass
	from (irb):2:in `a'
