What version of JavaScript will IE 7.0 support?

Firefox 1.5 supports JavaScript 1.6 (including its new E4X feature for XML programmers). IE 6.0, which is a few years older, supports JavaScript 1.3.

Is Microsoft planning to upgrade to the IE JavaScript to 1.6, or least something newer than 1.3? If so, which version of JavaScript will they be supporting in IE 7.0 if/when it ships?

    don't worry about version levels. Worry about features

    if you want to know if this JS has that feature you code it like:

    if (window.XMLHttpRequest) { // Mozilla, Safari, standards!

    http_request = new XMLHttpRequest();
