PLEASE TRY TO FIX THE CODE

Answer 1

function start(){

// Go to the top of the stairs

for(var i = 0; i < 4; i = i + 1){

climbStep();

}

// Go down the slide

for(var i = 0; i <= 4; i = i + 1){

getABall();

}

}

// Rest of the code remains the same

Step-by-step explanation:

there are some issues with the incrementation of the loop variable 'i' in the first for loop. The correct way to increment 'i' by 1 is to use 'i = i + 1' or the shorthand 'i++'.
