iconv-lite VS Numeral-js

Then, the Text (or call it String) class is also a List. There are 3 types of Text classes: Text8, Text16 and Text32. Notice I was kind of vague in what I meant there. Take Text8 for example. Using Text8, we have many different encodings. We have the UTF8 encoding, as well as many other "single byte encodings" like ASCII.

I won't go into detail about how to map a character into its Shift JIS code for now, as there are good libraries for the job (iconv-lite comes to mind, and you can even have a look to the actual table if you want to whip up your own solution). It's sufficient to say that we'll need 13 bits (213 = 8192) for each one of them.

For Kanji mode... oh dear. First, we'd have to get the Shift JIS code of the pictogram, and the best way to do it is using a library like iconv-lite or, if you want to to it on your own, use its symbol table. Also, not every symbol can be used, but only those in the ranges 0x8140 to 0x9FFC and 0xE040 to 0xEBBF. In the end, a Kanji character will take 13 bits.

You can use a third-party library, which is a bunch of code that someone else wrote for you. Many awesome third-party libraries can format numbers with commas in JavaScript. For example, you can try Numeral.js, Accounting.js, or Format.js.

JavaScript provides built-in methods like toFixed() for number formatting, as well as libraries like numeral.js, which provides advanced formatting options. These methods and libraries can be used to format numbers in a variety of ways, including currency, percentages, and time. It's important to note that the way numbers are formatted can vary depending on the locale and currency, so it's important to be mindful of these considerations when formatting numbers in JavaScript.

The `a` at the end handles automatically shortening it. See the last example in [the docs for numeraljs](http://numeraljs.com/) under the "Format > Currency" section.

Long answer: The format part of tprintf roughly follows sprintf-js and the numbers are formatted using ns.nFormat which uses the syntax from numeraljs.com.

Numeral

However, there are always great libraries that the community develops to support missing features, such as dinero.js, currency.js, and numeral.js.

It's worth mentioning that to communicate your data better to your user, it's always a good idea to mix and match different types of data visualizations. Moreover, you can also have a date formatting library (such as Moment.js) or number formatting library (such as numeral.js) that could accompany your graphs and highlight any special or outstanding number in your dataset.
