How to use SolverJS?

SolverJS is a comprehensive JavaScript package that provides a range of functions to help us solve common math problems. We know that web applications often require complex logic to function properly, and these logical solutions can easily become long and difficult to manage. This is where Solver JS comes in - it includes a wide range of general and complex mathematical solutions and provides functions not available in standard JavaScript.

In this tutorial, we will learn how to use Solver JS and its various functions. The package includes functions such as date conversions, keyword extraction, string case checking, URL shortening, and much more.

Installation

First, create a new Node.js project by running npm init in the terminal. This will create a new package.json file for our project.

npm init

Next, install the SolverJS package by running the following command:

npm install solverjs

Basic Usage

Once installed, import the functions you want to use at the top of your JavaScript file. For example, to use the add function:

const { add } = require('solverjs');

const sum = add(2, 3);
console.log(sum);

Email Validation Example

SolverJS provides utility functions for data validation. Here's how to check if a string is a valid email address:

const { isEmail } = require('solverjs');

const email = 'example@domain.com';
const isValidEmail = isEmail(email);
console.log(isValidEmail);

true

Available Methods

SolverJS provides many useful functions and common logic solutions. Here are some of the main categories:

String Manipulation Methods

• capitalize ? capitalizes the first letter of a string
• isLowerCase ? checks if all letters in a string are lowercase
• isUpperCase ? checks if all letters in a string are uppercase
• reverseString ? reverses the order of characters in a string
• truncate ? truncates a string to a specified length and adds ellipses

Mathematical Methods

• isPrime ? checks if a number is a prime number
• findFactors ? finds all factors of a given number
• sum ? finds the sum of a given array of numbers
• product ? finds the product of a given array of numbers

Date/Time Methods

• getAge ? calculates the age of a person based on their birthdate
• getDaysBetweenDates ? calculates the number of days between two dates
• getTimeFromDate ? returns the time from a given date as a string

Example: Keyword Extraction

The keywordExtractor function extracts keywords from a given text and returns an array of keywords:

const solverjs = require('solverjs');
const text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis suscipit lacus ac urna eleifend pharetra.";
const keywords = solverjs.keywordExtractor(text);
console.log(keywords);

Example: Armstrong Number Check

The isArmstrong function determines whether a given number is an Armstrong number. It returns a boolean value:

const solverjs = require('solverjs');

// Check if numbers are Armstrong numbers
console.log(solverjs.isArmstrong(153));
console.log(solverjs.isArmstrong(9474));
console.log(solverjs.isArmstrong(123));

true
true
false

Example: Date to Day Conversion

The dateToDay function takes a date string and returns the corresponding day of the week:

const solverjs = require('solverjs');

console.log('The day is: ' + solverjs.dateToDay('01/01/2000'));

The day is: Saturday

Conclusion

SolverJS provides a convenient way to simplify complex code and increase developer productivity. By using the functions provided by SolverJS, you can reduce development time and focus on building high-quality applications with ready-made mathematical and utility functions.
