# Introducing VfyJS: 

## Simplifying Data Validation and More

**VfyJS** is a robust JavaScript library designed to streamline data validation, string manipulation, and error handling in your projects. Whether you're handling user inputs, configuration data, or API responses, VfyJS offers a comprehensive set of utilities to ensure data integrity and enhance code reliability.

## What is VfyJS?

At its core, VfyJS provides a set of functions and tools to validate data, manipulate strings, and handle errors effectively. It simplifies common tasks that developers often face, allowing you to concentrate on building robust applications without compromising data integrity.
### In Node.js

After installing the package, you can import it into your Node.js application. Below is an example demonstrating how to use vfyjs for password validation:

```javascript
const vfyjs = require('vfyjs');

// Example usage
const data = '123!#@ScsA';
const validationResult = vfyjs.isPassword(data);
console.log(validationResult);
```
The `isPassword` function checks whether the provided string meets the criteria for a valid password. Adjust the `password` variable with your actual password data for validation.

### In Browser

To utilize vfyjs in a browser environment, include the `vfyjs.browser.js` script in your HTML file:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Your Webpage</title>
</head>
<body>
    <!-- Include vfyjs script -->
    <script src="path/to/vfyjs.browser.js"></script>
    <script>
        // Example usage in browser
        const data = '123!#@ScsA';
        const validationResult = vfyjs.isPassword(data);
        console.log(validationResult);
    </script>
</body>
</html>
```

Ensure to replace `"path/to/vfyjs.browser.js"` with the correct path relative to your HTML file.

## How to Use VfyJS

1. **Installation:**
   ```bash
   npm install vfyjs
   ```

2. **Usage Example:**
   ```javascript
   const { validatePhoneNumber, getSubstring, trimValue, HandleError } = require('vfyjs');

   // Validate a phone number
   validatePhoneNumber('1', '1234567890').then(result => {
      console.log(result);
   });

   // Get a substring
   const inputString = "Hello, World!";
   const result = getSubstring(inputString, [0, 5], [7, 12]);
   console.log(result); // Hello-World

   // Trim a value
   const inputString = ' H ell o, World! ';
   const result = trimValue(inputString);
   console.log(result); // Output: 'Hello, World!'

   // Handle an error
   const userAge = '25'; // Note: '25' is a string, not a number
   try {
       HandleError.IfNotType('number', userAge, 'Age should be a number');
       console.log('Age is valid.');
   } catch (error) {
       console.error(error.name); // 'TypeError'
       console.error(error.message); // 'Age should be a number'
   }
   ```
