How to use the rambda.equals function in rambda

  jsv.property('composes two functions', jsv.fn(), jsv.fn(), jsv.nat, (f, g, x) => R.equals(R.compose(f, g)(x), f(g(x))))

Just.prototype.equals = function(x){
      return x instanceof Just && R.equals(x.value, this.value)
    }
    eq(R.uniq([ -0, -0 ]).length, 1)
