Pokémon EV Calculator (Vanilla JS)

An interactive web application to calculate Pokémon EV (Effort Value) distribution based on your desired stats, available items (Vitamins, Mochi, Feathers), and in-game currencies. It helps optimize item usage and plan purchases to reach your EV goals efficiently.

This version is built with HTML, CSS (Tailwind via CDN), and Vanilla JavaScript, making it directly deployable on platforms like GitHub Pages without any build process.

🌟 Key Features

• Comprehensive EV Configuration:
  • Set Current EVs for your Pokémon.
  • Define Target EVs for each stat (HP, Attack, Defense, Sp. Attack, Sp. Defense, Speed) using intuitive sliders.
  • Visual progress bar for Total Target EVs, preventing allocation beyond the 510 maximum.
  • Individual stat cap of 252 EVs enforced.
  • "Reset All Target EVs" button for quick clearing.
• Inventory Management:
  • Input quantities for owned Vitamins, Mochi, and Feathers.
  • Collapsible sections for easy organization.
  • Quick increment/decrement buttons (+/-) for item quantities.
• Currency Tracking:
  • Enter your available Poké Dollars and League Points.
  • Vitamins are priced at 10,000 (Poké Dollars or LP).
• Smart Item Optimization & Purchase Planning:
  • The calculator first utilizes your existing inventory (Vitamins, then Mochi, then Feathers) to meet EV goals.
  • If owned items are insufficient, it suggests purchasing the required Vitamins.
  • Granular Purchase Logic:
    • Calculates the exact number of Vitamins needed per stat.
    • Checks affordability against your combined currencies (Poké Dollars prioritized).
    • If you can't afford all suggested Vitamins for a stat, it tells you how many you can buy with remaining funds.
    • Clearly indicates any partial purchases and the remaining quantity/cost needed for that specific item.
• Detailed & User-Friendly Results:
  • Overall Status: Clear message indicating if EV goals were met.
  • Purchase Overview: Summarizes total ideal cost, actual amount spent, and total additional currency needed if goals aren't fully met.
  • Per-Stat Breakdown: Details items used from inventory and Vitamins to purchase (including partial/unaffordable).
  • Important Notes & Warnings: Highlights any shortfalls or issues.
• Visual Appeal:
  • Uses item sprites from PokeAPI where available, with emoji fallbacks.
  • Themed colors for stats and UI elements (via Tailwind CSS).
  • Responsive design.
