Cannot read property of "x"

Question

It kept saying that the property of x is undefined, but this event would occur temporarily. When the bullet collides with the ufo. How could i fix that?
for(var i = 0; i < numberOfFruits; i++){
const bulletsShooting = bullets.filter(element => element.isShooting === true)
for(var bulletShooting of bulletsShooting){
if(Collide(bulletShooting, fruits[i])){
fruits.splice(fruits.indexOf(fruits[i]), 1)
numberOfFruits -= 1
player.score += 10
}
}
}

Answer 1

If the error isn't persistent, then I think the problem is when you're updating the number of fruits,
`i < numberOfFruits` is slower so collision function tends to collide with an undefined fruit, so it'll be better to loop backward
for (I = numberOfFruits; I > -1; I--)
Also, do expect the unexpected console error message when writing games, so always add this to stop all console errors when you're ready to publish your code
onerror = () => {};
console.log = () => {};
console.error = () => {};
