Question regarding result consistency for <= and == with arrays

[csknns]

I was trying to implement a jsonlogic library in Swift, and I wanted the library to provide results similar to your json-logic. Playing around in http://jsonlogic.com/play.html I found that:
{ "<=" : [[1], [1]] } results in true
but
{ "==" : [[1], [1]] } results in false
and
{ "===" : [[1], [1]] } results in false
and
{ "<" : [[1], [1]] } results in false

I am trying to understand if this the correct and intended behavior, because it is hard to wrap my head around these results.
