its not passing

Welcome back to the forum @saptarshimondal.mail

You are asked to check for a truthy value.

For next time, describe the issue in your own words. Learning to communicate problems is a part of becoming a web developer.

Happy coding

we are here to get the truthy value, after looking for the every syntax we can also write this: if (collisionDetectionRules.every(Boolean)) {
player.velocity.y = 0;
return;
}

Couldn’t solve it yet, any hints will be helpful. I have also tried: if(collisionDetectionRules.every(Boolean)) {

player.velocity.y = 0;
return;
}

consider, what is the value of rule? do you need to pass it to Boolean to get a truthy/falsy value?
