using extend script to push a variable into an array it's basically javascript. any idea what I am doing wrong?

if ( app.documents.length > 0 ) {

    for ( i = 0; i< app.activeDocument.textFrames.length; i++) {
         var allSizes = []; //set up empty array

        textArtRange = app.activeDocument.textFrames[i].textRange;
        var fontName =  textFonts.getByName("Nobile");
        alert (fontName);
        textArtRange.characterAttributes.textFont = fontName;
        var fontSizes = textArtRange.characterAttributes.size;

        allSizes.push(fontSizes)
        alert (fontSizes);

    }
        alert (allSizes);
}

the alerts for allSizes only return single values, not the array.

Move the definition of allSizes = [] outside the loop.

Currently, you're "resetting" the value of allSizes at each loop.

You're setting up the empty array inside of the for loop. It's resetting it each time. Move it above the for loop:

var allSizes = []; //set up empty array
for ( i = 0; i< app.activeDocument.textFrames.length; i++) {
     .....
