The TypeError() constructor creates TypeError objects.
new TypeError()
new TypeError(message)
new TypeError(message, options)
new TypeError(message, fileName)
new TypeError(message, fileName, lineNumber)
TypeError()
TypeError(message)
TypeError(message, options)
TypeError(message, fileName)
TypeError(message, fileName, lineNumber)
Note: TypeError() can be called with or without new. Both create a new TypeError instance.
message Optional
Human-readable description of the error
options Optional
An object that has the following properties:
cause Optional
A property indicating the specific cause of the error. When catching and re-throwing an error with a more-specific or useful error message, this property can be used to pass the original error.
fileName Optional Non-standard
The name of the file containing the code that caused the exception
lineNumber Optional Non-standard
The line number of the code that caused the exception
try {
null.f();
} catch (e) {
console.log(e instanceof TypeError); // true
console.log(e.message); // "null has no properties"
console.log(e.name); // "TypeError"
console.log(e.stack); // Stack of the error
}
try {
throw new TypeError("Hello");
} catch (e) {
console.log(e instanceof TypeError); // true
console.log(e.message); // "Hello"
console.log(e.name); // "TypeError"
console.log(e.stack); // Stack of the error
}
