Language: TypeScript
Severity: Error
Category: Best Practices
In JavaScript, -0
and +0
are considered to be equal ((-0 === +0) // true
). However, they behave differently in some operations. For instance, 1/-0
results in -Infinity
, while 1/+0
results in +Infinity
. Directly comparing with -0
can produce results that are hard to understand, and may lead to bugs.
