try/catch es10

An update for developer convience allows the use of try/catch without an explicit e Error reference in the catch call.

// Before
try {
  fetch('https://example.com')
} catch (e) {
  console.log(`e`)
}

// After
try {
  fetch('https://example.com')
} catch {
  console.log(`something wrong.`)
}
