My first time writing an npm package/JS library

What will it expose?

Need setters on these to do bounds checks and overflows

strict When on, creating an LSD with out-of-bounds numbers (pence over 12, shillings over 20) will raise an error When off, it will do its best to make sense in a “pile of coins” way

An lsd class

{ ‘pounds’ : number, ‘shillings’ : number, ‘pence’ : number }

What tech shall we use?

typescript

Methods

Repo: https://github.com/SteGriff/old-money

SteGriff/old-money

looked at uvu ... too weird

+ addPence, + addShillings, + addPounds

a test runner...

override toString() to get a value like £1 9s 6d

Properties

L E A R N I N G S

...or you can specify a format string of your own

Future

totalPence()

ava looks good, shame it has so many dependencies... I’ll go with it.

Constructors

ava?

new lsd(pence) new lsd(£, s, d) new lsd(string) ?
