One of the best ways to format numbers in JavaScript for cryptocurrency prices is to use the toLocaleString() method. This method allows you to specify the desired locale and options for formatting the number. For example, you can use the 'en-US' locale to format the number with the appropriate currency symbol and separators for thousands. Additionally, you can use the minimumFractionDigits and maximumFractionDigits options to control the number of decimal places. By using this method, you can ensure that the numbers are accurately formatted and easy to read.
