Optionaloptions: ErrorOptionsReadonlyattemptsOptionalcauseOptionalstackStaticstackThe Error.stackTraceLimit property specifies the number of stack frames
collected by a stack trace (whether generated by new Error().stack or
Error.captureStackTrace(obj)).
The default value is 10 but may be set to any valid JavaScript number. Changes
will affect any stack trace captured after the value has been changed.
If set to a non-number value, or set to a negative number, stack traces will not capture any frames.
StaticcaptureCreates a .stack property on targetObject, which when accessed returns
a string representing the location in the code at which
Error.captureStackTrace() was called.
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack; // Similar to `new Error().stack`
The first line of the trace will be prefixed with
${myObject.name}: ${myObject.message}.
The optional constructorOpt argument accepts a function. If given, all frames
above constructorOpt, including constructorOpt, will be omitted from the
generated stack trace.
The constructorOpt argument is useful for hiding implementation
details of error generation from the user. For instance:
function a() {
b();
}
function b() {
c();
}
function c() {
// Create an error without stack trace to avoid calculating the stack trace twice.
const { stackTraceLimit } = Error;
Error.stackTraceLimit = 0;
const error = new Error();
Error.stackTraceLimit = stackTraceLimit;
// Capture the stack trace above function b
Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
throw error;
}
a();
OptionalconstructorOpt: FunctionStaticisIndicates whether the argument provided is a built-in Error instance or not.
Staticprepare
An error class representing a failed retry operation.
表示重试操作失败的错误类。
Param: attempts
The number of attempts. 尝试次数
Param: message
The error message. 错误消息
Remarks
The constructor clamps the
attemptsparameter to a non-negative integer usingMath.max(0, Math.trunc(attempts)). Negative values are silently converted to 0, and fractional values are truncated.构造函数会通过
Math.max(0, Math.trunc(attempts))将attempts参数钳位为非负整数。负值会被静默转换为 0，小数值会被截断。Example
