OptionalcauseThe cause of the error.
A detailed description of the error.
The error message indicating the class is not a function.
OptionalstackStaticstackThe maximum number of stack frames to capture.
Returns a string representation of an object.
StaticcaptureCreate .stack property on a target object
OptionalconstructorOpt: FunctionCreates 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: FunctionStaticisCheck if a value is an instance of Error
The value to check
True if the value is an instance of Error, false otherwise
Staticprepare
Error thrown when a provided class is not a function constructor.
Example
Param: className
The name of the class that is not a function constructor.
