Answer 1

To display price/currency without decimal point or fraction digits, use Intl.NumberFormat with a few parameters maximumFractionDigits and minimumFractionDigits set to 0.

An example:

new Intl.NumberFormat(undefined, { 
  style: 'currency', 
  currency: 'USD',
  maximumFractionDigits: 0, 
  minimumFractionDigits: 0, 
}).format(1050.55)
