Created by Niels Provos and David Mazières, it's based on the Blowfish cipher and incorporates a salt to protect against rainbow table attacks. Bcrypt's key feature is its adaptive nature, allowing for the adjustment of its cost factor to make it slower as computational power increases, thus maintaining resistance against brute-force attacks over time. It produces a fixed-size hash output, typically 60 characters long, which includes the salt and cost factor. Bcrypt is widely used in many programming languages and frameworks due to its security strength and relative ease of implementation. Its deliberate slowness in processing makes it particularly effective for password storage, where speed is not a priority but security is paramount.\n\nVisit the following resources to learn more:",

     "description": "Rust is a systems programming language that focuses on safety, concurrency, and performance. Developed by Mozilla Research, Rust combines low-level control over system resources with high-level abstractions, preventing common programming errors like null or dangling pointer references at compile-time. It features a borrow checker for managing memory and preventing data races, making it ideal for building reliable and efficient software. Rust's zero-cost abstractions, pattern matching, and trait-based generics offer powerful tools for expressing complex ideas clearly. While primarily used for systems programming, web assembly, and game development, Rust's growing ecosystem supports various domains. Its emphasis on memory safety without sacrificing performance makes it increasingly popular for developing secure, high-performance applications in fields ranging from operating systems to web services.\n\nVisit the following resources to learn more:",

It allows developers to enhance their CSS workflow by automating repetitive tasks, adding vendor prefixes, and implementing future CSS features. PostCSS works as a preprocessor, but unlike Sass or Less, it's highly modular and customizable. Users can choose from a wide range of plugins or create their own to suit specific needs. Popular plugins include Autoprefixer for adding vendor prefixes, cssnext for using future CSS features, and cssnano for minification. PostCSS integrates well with various build tools and can be used alongside traditional CSS preprocessors. Its flexibility and performance make it a popular choice for optimizing CSS in modern web development workflows.\n\nVisit the following resources to learn more:",

We could try to catch that `bleu` typo by using a type annotation on palette, but we’d lose the information about each property.\n\n    type Colors = 'red' | 'green' | 'blue';\n    type RGB = [red: number, green: number, blue: number];\n    \n    const palette: Record<Colors, string | RGB> = {\n      red: [255, 0, 0],\n      green: '#00ff00',\n      bleu: [0, 0, 255],\n      //  ~~~~ The typo is now correctly detected\n    };\n    // But we now have an undesirable error here - 'palette.red' \"could\" be a string.\n    const redComponent = palette.red.at(0);\n    \n\nThe `satisfies` operator lets us validate that the type of an expression matches some type, without changing the resulting type of that expression. As an example, we could use `satisfies` to validate that all the properties of palette are compatible with `string | number[]`:\n\n    type Colors = 'red' | 'green' | 'blue';\n    type RGB = [red: number, green: number, blue: number];\n    \n    const palette = {\n      red: [255, 0, 0],\n      green: '#00ff00',\n      bleu: [0, 0, 255],\n      //  ~~~~ The typo is now caught!\n    } satisfies Record<Colors, string | RGB>;\n    \n    // Both of these methods are still accessible!\n    const redComponent = palette.red.at(0);\n    const greenNormalized = palette.green.toUpperCase();\n    \n\nLearn more from the following resources:",

+
+The goal of this project is to help you learn about how to use external packages using [npm](https://www.npmjs.com/). The user inputs their birthdate via a [JavaScript Datepicker](https://www.npmjs.com/package/js-datepicker), and the app calculates and displays their exact age, including years, and months using [Luxon](https://www.npmjs.com/package/luxon).
+
+![Age Calculator](https://assets.roadmap.sh/guest/age-calculator-do1un.png)
+
+## Requirements
+
+You are required to develop an age calculator with the following features:
+
+- A form that allows users to input their birthdate using a JavaScript datepicker (avoid the default HTML date picker)
+- Use the [Luxon](https://www.npmjs.com/package/luxon) library to calculate the exact age in years, months, and days
+- Display the result on the same page after the user submits the form
+- Implement basic validation to ensure the birthdate is valid
+- Use simple styling to make the calculator visually appealing and responsive
+
+<hr />
+
+This project will help you understand how to manipulate dates and times in JavaScript using [Luxon](https://www.npmjs.com/package/luxon). You'll gain experience handling user input via a datepicker, performing date calculations, and designing a simple user interface.
