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.fileName);            // "Scratchpad/1"
  console.log(e.lineNumber);          // 2
  console.log(e.columnNumber);        // 2
  console.log(e.stack);               // "@Scratchpad/2:2:3\n"
}

Creating an URIError

try {
  throw new URIError('Hello', 'someFile.js', 10);
} catch (e) {
  console.log(e instanceof URIError); // true
  console.log(e.message);             // "Hello"
  console.log(e.name);                // "URIError"
  console.log(e.fileName);            // "someFile.js"
  console.log(e.lineNumber);          // 10
  console.log(e.columnNumber);        // 0
  console.log(e.stack);               // "@Scratchpad/2:2:9\n"
}
