The URIError() constructor creates URIError objects.
new URIError()
new URIError(message)
new URIError(message, options)
new URIError(message, fileName)
new URIError(message, fileName, lineNumber)
URIError()
URIError(message)
URIError(message, options)
URIError(message, fileName)
URIError(message, fileName, lineNumber)
Note: URIError() can be called with or without new. Both create a new URIError instance.
message Optional
Human-readable description of the error.
options Optional
An object that has the following properties:

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 {

}
try {
throw new URIError("Hello");
} catch (e) {
console.log(e instanceof URIError); // true
