JS ⟩ value ⟩ function ⟩ function boundary

(related to function scope) 🚧

⭐️ 重點

break / continue

• won't operate across an IIFE function boundary to control an outer loop / block.

📗 You Don't Know JS Yet: Scopes & Closrues

if the code you need to wrap a scope around has return / this / break / continue in it：

• don't use function / IIFE (which has its own function boundary)❗

• use block instead.
