Correct way to create an array with N number of elements without the old 'new Array(N)'?

Whenever I work with arrays, I always use the [] style, however, when I want to create an array with a fixed amount of elements I use new Array(N) (I don't know any other way of doing this)

I thought it wasn't big deal, until I read these strong words about this:

Anyone doing this, using “new Array()” instead of “[]“, or “new Object()” instead of “{}” needs to relearn JavaScript.

I really want to avoid writting bad code. Anyone mind tell me the right direction to go?

function repeat(str, len){
    str= str || '';
    len= len || 1;
    return Array(len+1).join(str);
}

repeat('*',25)

// returned value: (String)
