coffeelint-prefer-english-operator-streamline
This is a custom rule for CoffeeLint extending prefer_english_operator
to
allow Streamline.js futures syntax (!_
).
It disallows use of symbolic operators such as ==
, !=
, &&
, ||
, and !
.
Instead, it recommends using is
, isnt
, and
, or
, and not
instead.
Double not !!
is allowed by default for boolean coercion but can be disallowed
via doubleNotLevel
configuration.
a is a # yes
a == a # no
a isnt a # yes
a != a # no
a and b # yes
a && b # no
a or b # yes
a || b # no
!!a # yes
not not a # yes
f !_ # yes
