My code includes an if statement inside a for loop that iterates over the entire array and displays its elements:
for (var i = 0; i < txtA.length; i++) {
txtA[i].update();
txtA[i].show();
if (txtA[i].y == height) {
txtA.pop();
console.log(txtA.length);
}
}
The issue arises when the if statement evaluates to true, causing all elements in the array to be removed. Can someone provide guidance on how to prevent this from happening?
When using a pop operation, the last element of the array is removed. If the first item reaches the bottom, it will trigger the removal of subsequent items in the array. This process continues until the first item that hit the bottom is removed.
It is recommended to use splice instead
txtA.splice(i, 1);
It seems like there may be a flaw in your reasoning. Without knowledge of the specific contents of the Array, it's challenging to pinpoint where the problem lies.
However, keep in mind that Array.prototype.pop is not the culprit for the issue you're encountering. As stated on MDN:
The pop method removes the last element from an array and returns that value to the caller... If you call pop() on an empty array, it returns undefined.
In other words, when using pop, it eliminates the last element from the Array or (in the case of an empty Array) does nothing and provides an undefined output; it doesn't actually delete the entire Array. So, if the goal is to clear the Array, then it must be removing elements one by one, popping off one element at a time from the end of the Array during each iteration.
