Blobbeginner

Blob.size — empty Blob

📖 Usage Example

const emoji = new Blob(['😀'])
emoji.size  // → 4 (UTF-8 encoding uses 4 bytes)

size counts bytes (UTF-8 encoded), not characters.

Empty Blob size

new Blob([]).size equals 0 — an empty parts array produces a zero-byte Blob.

Challenge: Verify new Blob([]).size === 0.
