@cjfulford/measurements-js

@cjfulford/measurements-js is an npm package providing classes for handling measurements of length and area in various units. This package offers flexibility and ease of use for converting, manipulating, and comparing measurements.

Installation

You can install @cjfulford/measurements-js via npm:

npm install @cjfulford/measurements-js

Usage

Length

Create a length object:

import {Length, LengthUnit} from '@cjfulford/measurements-js';

// Create a length object
const length = new Length(5, LengthUnit.METRE);

// Perform operations
const convertedLength = length.add(2, LengthUnit.KILOMETRE);
console.log(convertedLength.kilometres); // Output: 2.005

// Compare lengths
console.log(length.isGreaterThan(4, LengthUnit.METRE)); // Output: true
const length2 = new Length(1, LengthUnit.KILOMETRE);
console.log(length.isLessThan(length2)); // Output: false

Area

Import Area and AreaUnit from @cjfulford/measurements-js:

Create an area object:

import {Area, AreaUnit} from '@cjfulford/measurements-js';

// Create an area object
const area = new Area(100, AreaUnit.SQUARE_METRE);

// Perform operations
const convertedArea = area.mulByNumber(0.5);
console.log(convertedArea.squareMetres); // Output: 50

// Compare areas
console.log(area.isLessThanOrEqualTo(200, AreaUnit.SQUARE_METRE)); // Output: true

There is also the LengthImmutable and AreaImmutable classes which are immutable versions of Length and Area.
