(== x)
(== x y)
(== x y & more)

Details:

This is an equality check for numbers of different types that was carried over from Clojure, to allow compatibility when converting code to ClojureScript.

Since there is only a single number type in JavaScript, 64-bit floating point, there is no reason to use the == operator in ClojureScript.

Behavior on non-number arguments is undefined.

Examples:

(== 1 1)
;;=> true

(== 1 2)
;;=> false

Source docstring:
Returns non-nil if nums all have the equivalent
value, otherwise false. Behavior on non nums is
undefined.
