InternalInternalStatic InternalstackThe 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.
Readonly InternalargsAdditional arguments for this instance, if any.
Readonly InternalcontextInternalmessageReadonly InternalnameRepresents the name for the type of error.
Protected Readonly InternaloptsOptional Readonly InternalcauseRepresents the cause of the error (e.g., a different exception that was caught).
Optional InternalstackProtected Optional Readonly InternalARGS_Default args object, if applicable.
StaticcaptureInternalCreates 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: FunctionStaticprepareInternalThe object shape used when converting to JSON.
InternalOverrides the default function to return a string representation of this object.
InternalOverrides the default function to return an object representation of this object.
Used to throw errors while compiling the tokens.
