JavaScript forEach 方法跳出循环的操作方法

for (let i = 0; i < 10; i++) {
  if (i === 1) {
    // 跳出本次循环，不会打印1
    continue
  }
  if (i === 3) {
    // 结束循环，不会打印3和之后的数字
    break
  }
  // 输出0 2
  console.log(i)
}

const numbers = [1, 2, 3, 4, 5]
numbers.forEach(number => {
  if (number === 2) {
    // 跳出整个循环
    break  // SyntaxError: Illegal break statement
  }
    console.log(number)
})

numbers.forEach(number => {
  if (number === 2) {
    // 跳出当前循环
    continue  // SyntaxError: Illegal continue statement: no surrounding iteration statement
  }
    console.log(number)
})

numbers.forEach(number => {
  if (number === 2) {
    // 跳出当前循环
    return 
  }
  console.log(number) // 1 3 4 5
}

for (const number of numbers) {
  if (number === 2) {
    continue
  }
  console.log(number) // 1 3 4 5
}

try {
  numbers.forEach(number => {
    if (number === 2) {
      throw new Error()
    }
    console.log(number) // 1
  })
} catch (error) {
  console.log('捕获到错误')
}
