JavaScript strings must be quoted with "
(QUOTATION MARK) or '
(APOSTROPHE) not “
(LEFT DOUBLE QUOTATION MARK) and ”
(RIGHT DOUBLE QUOTATION MARK).
This error is typically caused by writing code using a word processor that automatically inserts typographic quotes.
Use a text editor designed for programmers (such as Sublime, Vim, Emacs, Komodo, TextMate, Notepad++, BBEdit, or Eclipse) instead.
