Improve currencies.js

Problem

Not much thought has been given to the file currencies.js. It was always planned that this file would be rewritten at some point, but one real simple and obvious issue with it is that it has an unnecessary function in it called symbol.

This is the entirety of the file:

const CURRENCIES = {
  'USD': '$',
  'EUR': '€',
  'BTC': 'Ƀ'
}

export const symbol = (code: string) => CURRENCIES[code] || code

export default CURRENCIES

Solution

• As a minimum, the function, which does a simple lookup, should be removed
• CURRENCIES should be exported directly, and not as the default export

This way, instead of doing:

import { symbol } from './utils/currencies.js'

// ...

var something = symbol('USD')

You'd do something more like:

import { CURRENCIES } from './utils/currencies.js'

// ...

var something = CURRENCIES.USD
