Why Formatus

There are snippets of code we keep writing everytime we want to create one tiny or huge app. Why keep repeating this snippets when you can get them all from one place? This is what formatus hopes to accomplish.

Basic Usage

First, import the package into the JavaScript file:

// importing formatus.
const formatus = require("formatus");
// or
const _ = require("formatus");
// either way works

// On Temperature
const kelvin = 2000;

kelcin.kelvinToCelcius();
// result => -73.15

// On Numbers
const count = 500000;
count.withSuffix();
// result => 500K

// On Array
const arrayList = [7000, 900, 10000, 49300];

list.arrayWithComma();
// result => [ '7,000', '900', '10,000', '49,300' ]

On Numbers

The functions from the numbers API are prototypes of the Number data type in JavaScript. The API functions will throw an error if used on value other than a number

// First import formatus
const _ = require("formatus");

const count = 200000;

count.withSuffix();
// result => 200K

The return type is a string

On Array

The functions from the array API are prototypes of the Array data type in JavaScript. The API functions will throw an error if used on value other than a array

// First import formatus
const _ = require("formatus");

const list = [2000, 100, 50000, 59300];

list.arrayWithComma();
// result => [ '2,000', '100', '50,000', '59,300' ]

The return values the array are of a string data type

For Temperature

The 4 supported temperature scales for conversion are Celcius, Kelvin, Fehrenheit, and Rankine.

Here is an example of how to convert between the 4

// From Kelvin to Celcius
const temp = 200;
// Conver from kelvin to celcius
const newTemp = temp.kelvinToCelcius();
// result => -73.15

// To convert back to celcius
newTemp.celciusToKelvin();
// result => 200

Pls note: The value returned always a string By default, the number of digit after the decimal point is always 2.

You can specify how many number of digit after the decimal you want by passing it in the function.

Example

// From Kelvin to Celcius
const temp = 200;

// One decimal place
temp.kelvinToCelcius(1);
// result => -73.1

// Integer
temp.kelvinToCelcius(0);
// result => -73
