Expected '!==' and instead saw '!='.
The '&&' subexpression should be wrapped in parens.
if (!ta.value || (ta.value != ta.defaultValue && confirm('Are you sure?')))
Since the textarea value and default value are always of the type string
Why should I add parenthesis when && has a higher precedence than ||?
Did you mean this:
if (!ta.value || (ta.value != ta.defaultValue && confirm('Are you sure?')))
or this:
if (!ta.value || ta.value != (ta.defaultValue && confirm('Are you sure?')))
The first one.
