javascript error array creation

this is the code

var xyzTris = [[[0,-3,4],[-2,0,4],[2,0,4]]];
console.log("zero: ",rdfTris);
var scrTris = [[[]]];
console.log("first: ",scrTris);
var rdfTris = [[[]]];
console.log("second: ",rdfTris);

What's strange is, the console out shows:

zero: undefined
first: Array [[[]]]
second: Array [[[0, -3, 4]]]

Anybody get why the rdfTris array is mal-defined?

I've tried all sorts of rearrangements, the parser just seems confused by rdfTris and xyzTris. I discovered this downstream when I was getting some weird array elements not defined later in the code. Stripped all that away to get to this.

You are logging the value of rdfTris on line 2, but you assign a value to rdfTris on line 5.

var xyzTris = [[[0,-3,4],[-2,0,4],[2,0,4]]];
console.log("zero: ",xyzTris);
var scrTris = [[[]]];
console.log("first: ",scrTris);
var rdfTris = [[[]]];
console.log("second: ",rdfTris);

The above should work as expected.
