break var function 示例 无效的例子 function f() { var x = 3; x += 4; return x; // return 语句立即退出当前方法 x -= 3; // 因而该语句从不会执行,即该语句为不可达语句 } function f() { return // 这条语句被视作 `return;` 3 + 4; // 因而此处该函数已经返回,该语句永不会执行...
Warnings will not be shown for semicolon-less returns if these statements follow it: throw break var function Examples Invalid cases function f() { var x = 3; x += 4; return x; // return exits the function immediately x -= 3; // so this line will never run; it is unreachable }...

因为return、throw、continue和break语句无条件地退出代码块,其之后的任何语句都不会被执行。不可达语句通常是个错误。 functionfn(){x=1;returnx;x=3;// this will never execute} Rule Details This rule disallows unreachable code afterreturn,throw,continue, andbreakstatements. ...
