¥What went wrong?

continue 语句可用于继续循环，在其他地方使用它们是语法错误。或者，你可以向 continue 语句提供 label 以继续使用该标签的任何循环 - 但是，如果标签未引用包含语句，则会引发另一个错误 语法错误：未找到标签，并且如果标签引用不是循环的语句 ，仍然会抛出语法错误。

¥continue statements can be used to continue a loop, and using them elsewhere is a syntax error. Alternatively, you can provide a label to the continue statement to continue any loop with that label — however, if the label does not reference a containing statement, another error SyntaxError: label not found will be thrown, and if the label references a statement that is not a loop, a syntax error is still thrown.

¥Examples

¥Using continue in callbacks

如果要在 forEach() 循环中继续进行下一次迭代，请改用 return，或将其转换为 for...of 循环。

¥If you want to proceed with the next iteration in a forEach() loop, use return instead, or convert it to a for...of loop.

array.forEach((value) => {
  if (value === 5) {
    continue; // SyntaxError: continue must be inside loop
  }
  // do something with value
});

array.forEach((value) => {
  if (value === 5) {
    return;
  }
  // do something with value
});

for (const value of array) {
  if (value === 5) {
    continue;
  }
  // do something with value
}
