🚀 Welcome to the coding challenge

💻 Context

You are on an Operating System and several paths of the filesystem are referenced in the registry.

The registry is an array of objects, each one representing a path.

A path is formed of:

• path: A string representing the location within its parent
• parent: The parent location
• level: The level needed to access this path

The users of this operating system are referenced in a users array of objects.

Each object representing a user is formed of:

• name: A string representing the user name
• level: A number representing the user access level

📝 Rules

All the work you provide must be within index.js.

The three functions you will have to implement are exported members of index.js.

You can and SHOULD reuse your previous task(s) to complete the next one(s), think about this exercise as a whole and not just independent questions.

✅ Your Tasks

1️⃣ Create a function returning all the absolute paths

Even if /toto/tata exists, /toto is a valid path that should be returned.

The exported function should be getAllPaths(registry) and return an array of objects where each object contains at least the key absolutePath.

2️⃣ Create a function checking the accessibility of a path for a specific user

The exported function should be hasAccess(user, path, paths) where user is a user object and path is a string.

The exported function should return a boolean, true if the user has access to the path, false otherwise.

Note: a nested path is accessible only if all the parent paths are accessible to the user.

3️⃣ Create a function listing and returning all the accessible paths for a specific user

The exported function should be getUserPaths(user, paths) where user is a user object.

The exported function should return an array of strings (paths).

Good luck! ✌️
