Device Information Analyzer

Build a device information analyzer that processes user agent strings to extract and categorize platform details for analytics purposes.

Requirements

Create a module that exports a function analyzeDevice(userAgent) which:

1. Extracts Platform Details: Parse the user agent string to determine the device's platform type (desktop, mobile, tablet, tv, or bot)

2. Identifies Device Vendor and Model: When available, extract the device vendor (e.g., Apple, Huawei, Samsung) and specific device model (e.g., iPhone, iPad, Kindle Fire)

3. Returns Structured Data: Return an object containing:

   • platformType: The platform type as a string
   • vendor: The device vendor (or null if not detected)
   • model: The device model (or null if not detected)
   • isBot: A boolean indicating if the device is a bot/crawler

4. Handles Invalid Input: Return null for invalid or empty user agent strings

Test Cases

• When given an iPhone user agent string, it returns platform type "mobile", vendor "Apple", and model "iPhone" @test

• When given an iPad user agent string, it returns platform type "tablet", vendor "Apple", and model "iPad" @test

• When given a desktop Chrome user agent string, it returns platform type "desktop" with vendor and model as null @test

• When given a bot user agent string (e.g., Googlebot), it returns isBot as true and platform type "bot" @test
