.some() method behaves unexpectedly

[bwaldon]

The following code returns true in the online WebPPL interpreter, but should return false:

var array = [{x:"x1", y:"y1"}, {x:"x1", y:"y2"}]

console.log(array.some(function(item){
  return(item.x === "x1" && item.y === "y3")
  }))

[null-a]

The problem here is that (a) array.some is calling out to a JS function and (b) the JS function is passed a webppl function as an argument, which isn't supported -- see point 2 here. (Of course, it would be nice if this was an error of some kind.) Instead, you can use the webppl function any. (Docs here.)

Missed this in the documentation — thanks!
