How do I prevent Javascript from running on certain pages

There are 3 scenes I do NOT want a certain Javascript code to run on.  How do I use IF, ELSE IF, and ELSE to accomplish this?  Here's the code I have right now.

-------------

$(document).on('knack-scene-render.any', function(event, scene) {

If (scene.key == 'scene_25'){}
Else if(scene.key == 'scene_33'){}
Else if(scene.key == 'scene_34'){}
Else {

<!--Start my Script-->
<!--End my Script-->

}

 

You are AMAZING, Sunny!  Thank you so much!!

 

But since you solved that puzzle so, so quickly, you need a more challenging one!  [This is sarcasm, of course!!]  If you can help me with the question at this link, it would be very helpful!  https://support.knack.com/hc/en-us/community/posts/360022208431-hide-menu

 

Just use below script 

 

$(document).on('knack-scene-render.any', function(event, scene) {
if (scene.key != 'scene_25' && scene.key != 'scene_33' && scene.key != 'scene_34') {
///add your code here
}
});
