break關鍵字會離開它所聲明的控制流最深的循環，停止進一步的迭代： > The break keyword leaves the control ?ow of the innermost loop (for or while) it is declared in, stopping further iterations: ~~~ while(true) { expression1; if (condition) break; expression2; } ~~~ 這里，expression1每個迭代都會被執行，但是當條件滿足，expression2則不再執行。 > Here,expression1 is evaluated for each iteration,but as soon as condition holds,expression2 is not evaluated anymore. 類型工具確保它只出現在一個循環中。break關鍵字在Haxe并不支持用于 switch case表達式（第5.17節）。 > The typer ensures that it appears only within a loop. The break keyword in switch cases (5.17) is not supported in Haxe.
