JS is love indeed

I 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.

@vishal-vp that's the saddest JS story I have heard 😂

@vishal-vp perhaps to understand JavaScript intricacies so you can avoid them in production code and not get bit in the ass?

I dont see inconsistencies? Every operator is doing exactly what it should.

But 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

@vishal-vp no wonder we have so many dropouts in cs

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

Then typescript change the clusterfucj

Just 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
