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"
