I have a variable:

var text = \"hello\";

I want to get the 0 positioned character, so:

var firstChar = text[0];

    Strings aren't accessible like arrays in IE (prior to IE9). Instead you can use charAt, which is available cross-browser:

    var text = "hello";
    var firstChar = text.charAt(0);
    // firstChar will be 'h'
