Great one, Gil. I truly appreciate your js skills. But the author hasn't mentioned this in his post, has he ? He is simply promoting the use of unary operator for string conversion instead of using parseInt( ), FOR WHICH he is receiving EECOLOR's criticism (and mine for that matter).
Even though I accept your point that in the case you mentioned above, where use of unary + is better than parseInt - I strongly disagree this is a real world scenario. We explicitly make a string variable to number only when we actually know it is going to be a number. If a developer would knew there is going to be a comma between the numbers they would be replacing those commas with nothing, which will produce correct results.
I agree that relying on the coercion method alone is dangerous and liable to produce errors.
Which is why I said in my previous post that almost any method of type coercion is vulnerable to failure unless the data is carefully sanitised beforehand.
