How to use Path module in Node.js?

The ‘path’ module in Node.js is used to handle and transform file paths. Here are some examples of it in use:

Importing the module
First, you should require the ‘path’ module before using it:

```
const path = require(‘path’);
```

Simple String Manipulations
- path.join() This method is used to join the specified input into a single path:

\`\`\`javascript const path = require(‘path’); console.log(path.join(‘/content’, ‘test’, ‘example.html’)); // Outputs: ‘/content/test/example.html‘ \`\`\`

- path.normalize() This method is used to normalize the specified path:

\`\`\`javascript const path = require(‘path’); console.log(path.normalize(‘/content///test///example.html’)); // Outputs: ‘/content/test/example.html‘ \`\`\`

Using Path Object
- path.dirname() This method returns the directory name of a path:

\`\`\`javascript const path = require(‘path’); console.log(path.dirname(‘/content/test/example.html’)); // Outputs: ‘/content/test‘ \`\`\`

- path.basename() This method returns the last part of a path:

\`\`\`javascript const path = require(‘path’); console.log(path.basename(‘/content/test/example.html’)); // Outputs: ‘example.html‘ \`\`\`

- path.extname() This method returns the extension of the path:

\`\`\`javascript const path = require(‘path’); console.log(path.extname(‘example.html’)); // Outputs: ‘.html‘ \`\`\`

Handle file paths
- path.resolve() This method resolves a sequence of paths or path segments into an absolute path:

\`\`\`javascript const path = require(‘path’); console.log(path.resolve(‘example.html’)); // Outputs: ‘/Users/yourusername/yourproject/example.html‘ \`\`\`

- path.isAbsolute() This method determines if path is an absolute path:

\`\`\`javascript const path = require(‘path’); console.log(path.isAbsolute(‘/Users/yourusername/yourproject/example.html’)); // Outputs: true console.log(path.isAbsolute(‘example.html’)); // Outputs: false \`\`\`

These are just some examples of what the ‘path’ module can do. You can refer to the Node.js documentation for more methods and usage.
