Scripting help please

I'm using an If/Else statement, Is there a way to say or? for example:

</p>

<p>if(Input.GetButton("Reload") // I want to say or BulletsFired >= 30)</p>

<p>

Use this:

function Update() {
    if (Input.GetButtonDown ("Fire1") || bulletsFired >= 30) {
        Reload() //This would be a function in your code called 'Reload' that reloaded your weapon.
}

If you need further help, don't hesitate to ask here. There is a script reference here as well, which has proven itself invaluable to me in coding JS.
