v-vp35356yI remember I was in a web development course where I was asked MCQ based on these inconsistencies. I mean, what is the fucking point of asking questions based on these.
-
Scipio6956y@vishal-vp perhaps to understand JavaScript intricacies so you can avoid them in production code and not get bit in the ass?
-
Liz37196yBut i get the behavior at least for the - since the + is a multifunctional operator in most high level languages for string concatenation while the - is not and js is weakly typed
-
Typescript fixes this by knowing what types your dealing with. Like what do you expect to happen when you add an int to a string ?

I feel it’s perfectly make sense.
String concat a number will return a string. Minus can only applies on numbers. What does ‘5’+-‘2’ even mean? String cannot subtract, so ‘5’+(-2) is squat to ‘5-2’.
‘5’+3-3=‘53’-3=50’
(5-3)+3=5 -
devios157706yJust use parseInt/parseFloat and stop whining. You’re doing math with strings and complaining that it’s weird.

All of these make perfect sense, except for Anon using an asterisk for an equals sign
