skips to the next iteration of the current/labeled loop.

JS ⟩ statement ⟩ control flow ⟩ continue

(statement) skip to the next iteration of the current / labeled loop.

continue;          // skips to next iteration of current loop
continue label;    // skips to next iteration of labeled loop

🧨 雷區

continue statement can be used only within the body of a loop, using it anywhere else causes a SyntaxError.

⭐️ 重點

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.

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

label is only used by break / continue.

if the code you need to wrap a scope around has return, this, break, or continue in it, don't use a function/IIFE(which has its own function boundary), use a block instead❗️
