Tell us what’s happening:

Task is to create if that uses the every method to check whether rules in array are truthy and if so set player’s velocity to 0.What is wrong?

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

if(collisionDetectionRules.every())
{ player.velocity.y=0;


return   }

// User Editable Region
