🔁loop

a statement that does something repeatedly.

JS ⟩ statement ⟩ loop

(statement) does something repeatedly.

⭐️ 重點

• continue ： skips to the next iteration of the current/labeled loop.

• break：breaks the current loop / switch or labeled statement entirely❗

👉 continue vs. break

(nested loop)

labeled statement is needed

• when you want to skip to the next iteration of an outer loop that is not the nearest enclosing loop.

• when you want to break out of a statement that is not the nearest enclosing loop / switch.

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