⚡ Why is pnpm Faster than npm?

Both are package managers, but pnpm wins in speed and efficiency due to how it stores and links packages.

🧠 Key Differences

1. 📦 Shared Global Store with Hard Links

• pnpm doesn’t duplicate packages across projects.
• Uses a global content-addressable store.
• Projects receive hard links to the global packages.

✅ Less disk space
✅ Faster install times

2. 🔒 Immutable Package Store

• Packages are read-only once installed.
• Guarantees safe, reliable caching.

3. 🧬 Strict Dependency Resolution

• Enforces that each package only accesses what it explicitly depends on.
• Helps avoid hidden bugs.

4. 🏎️ Faster Repeated Installs

• Cached packages make reinstalling almost instant.
• No need to re-download or re-copy files.
