TypeScript如何处理异常？

try {
  // 可能抛出异常的代码块
} catch (error) {
  // 处理异常
}

function divide(x: number, y: number): number {
  if (y === 0) {
    throw new Error("Divide by zero");
  }
  return x / y;
}

try {
  // 可能抛出异常的代码块
} catch (error) {
  // 处理异常
} finally {
  // 清理操作
}

class CustomError extends Error {
  constructor(message: string) {
    super(message);
    this.name = "CustomError";
  }
}

function foo() {
  throw new CustomError("Something went wrong");
}
