Given it’s JavaScript, which was expressly designed to carry on regardless, I could see an argument for it returning NaN, (or silently doing what Perl does, like I mention in a different comment) but then there’d have to be an entirely different way of concatenating strings.
I’m surprised they didn’t borrow OnErrorResumeNextfrom Visual Basic. Which was wrongly considered to be the worst thing in Visual Basic - when the real worst thing was OnErrorResume. OnErrorResumeNext at least moved on to the next line of code when an error occurred; OnErrorResume just executed the error-generating line again … and again … and again … and again …
You’re right. I’ve got too much Perl on the brain and forgot my roots. There is a language that does what you’re talking about with the ‘+’ operator: BASIC
Good luck getting the same thing retrofitted into JavaScript though. I can imagine a large number of websites would break or develop mysterious problems if this (mis)behaviour was fixed.
Nor would I expect “1312” to equal “1213”… Still that operator with these operands should just throw an exception

I don’t think there’s a way to retrofit JS - but php versions are deprecated all the time. Why not do the same with client-side script versions? :)
