URIError(message)
URIError(message, options)

Examples
Catching an URIError
try {
decodeURIComponent("%");
} catch (e) {
console.log(e instanceof URIError); // true
console.log(e.message); // "malformed URI sequence"
console.log(e.name); // "URIError"
console.log(e.stack); // Stack of the error
}
Creating an URIError
try {
throw new URIError("Hello");
} catch (e) {
console.log(e instanceof URIError); // true
console.log(e.message); // "Hello"
console.log(e.name); // "URIError"
console.log(e.stack); // Stack of the error
}
