}禁止使用空的块语句。
空的块语句是合法的,但通常表示某些内容被遗漏,从而可能降低代码的可读性。此规则忽略仅包含注释的块语句。此规则也忽略空的构造函数和函数体(包括箭头函数)。
无效:
if (foo) {}
while (foo) {}
switch (foo) {}
try {
doSomething();
} catch (e) {
} finally {
}
有效:
if (foo) {
// 空
}
while (foo) {
/* 空 */
}
try {
doSomething();
} catch (e) {
// 无论错误如何,继续
}
try {
doSomething();
} finally {
/* 无论错误如何,继续 */
}
