Or a Greek capital letter Lambda: Λ Λ(['1', '2', '3'])

  How does one type that?

    Like this: Λ ;) Windows: Alt+x 03BB Linux: Ctrl+Shift+u 03BB (still pressing Ctrl+Shift)

  Is that a valid variable name? Would that mean Λ is unicode?
  • mynegation 12y ago
    It is a valid Unicode letter so should be acceptable in EcmaScript 5.
