Are javascript arrays initialized to 0 explicit?

I need a typed array, in particular Float32Array, of all zeros. I thought that I would have to clean it manually, but I noticed that when I announced this, it was already reset. Is this something that is specified in the specification? Can I rely on this behavior?

According to the Typed Array JavaScript Specification, content is initialized to 0 . Therefore, you should be able to rely on this behavior.

Keep in mind that typed arrays do not yet have very good cross browser support . Chrome, Safari, Firefox, and Opera support it, but Internet Explorer only introduces support in IE10.
