learnyounode-golf: A JavaScript repository from rickycodes

Learnyounode as code golf ⛳

My attempt at solving learnyounode with the least amount of code possible

Why?

For fun!

Notes

drop spaces and semicolons where possible
drop var,let,const,new,function keywords where possible
make use of one letter variable names, eg: a=[]
utilize ternary and && to do "FP" things, eg: x&&y() vs if(x)y()
concat vs using toString(), eg: ''+d vs d.toString()
+ vs Number(), eg: +'200' vs Number('200')
store as ref if something is being used more than once, eg: l=console.log;l(a);l(b)
consider above when accessing object methods, eg: f='forEach';a[f](a=>…);b[f](b=>…)
use node internals, eg: .Server() vs .createServer()
use multiple lines if the column gets too wide
loose equality vs strict
replace true and false with 1 and 0

Contributing

Can you do better? Make a PR! If you can get the solutions down to less characters, be sure to run npm run build:mock && npm run test:mock && npm run test:solutions (this will create a new mock file with character counts and ensure both tests pass!). After that be sure to run npm run build:readmes to generate new README.md files for your newly added solutions.

Tests

run all tests:
npm t

test all solutions:
npm run test:solutions

test character counts:
npm run test:mock
