[Suggestion]: Improvements on currency parser & rules.

[MarketingPip]

The currency parser seems to need some work. Things like ("Five cents") or ("5 dollars") just return "5"...

Plus we should be adding rules for all things like "(one|five|ten) (dollar|dollars) bill".

That said - throwing this here! (Thinking this should be the new .get() ) etc...

function extractCurrencys(str) {
   let doc = nlp(str).money().json();
  let currencies = []

 for(let item in doc){
   let currency = doc[item]
   const unit = currency?.number?.unit;  // we need to replace units with only (dollars/cents, exchanges like USD etc...)
    const text = currency?.text;
   if(unit && text){
     currencies.push({text,unit})
   }

 }
  return currencies
}

console.log(extractCurrencys("$1 dollar to $2 dollar")) 

If you want to hack on this alone - you're more than welcome. Or you want to work on it together. More than fine.

Leaving this here for self - WIP:

function extractCurrencys(str) {
   let doc = nlp(str).money().json();
  let currencies = []

 for(let item in doc){
   let currency = doc[item]
   let unit = currency?.number?.unit;  // we need to replace units with only (dollars/cents, exchanges like USD etc...)
    const text = currency?.text;

   if(unit && !nlp(currency.number.unit).has("#Currency")){
     unit = null;
   }

   if(unit && text){
     currencies.push({text,unit})
   }

    if(!unit && text){
     currencies.push({text,unit:null})
   }

 }
  return currencies
}
