How do I loop backwards?

Question

For example forward loop is done thus; function move(){(if pos >= 1050) {clearInterval (a); } else {pos++; moving.style.left = pos+ 'px';}}

Answer 1

start from where you stop to where you begin by decreesing the initialization value

Answer 2

Pls can you drop an example?

Answer 3

Can you please tell me which language you are using?
For C++, Java, PHP, JavaScript, C# and C this works:

for (int i = 5; i > 0; i--){
// i will always be one smaller
}

For Python:
for i in range(5, 1, -1):
print(str(i))
#Output 5 4 3 2
NOTE: the "-1" is necessary! (Step)

Backwards iteration in Ruby: https://stackoverflow.com/questions/2070574/is-there-a-reason-that-we-cannot-iterate-on-reverse-range-in-ruby

For kotlin:
for (n in 100 downTo 1) {
//Do something
}

For Swift:
for index in stride(from: 5, to: 1, by: -1) {
print(index)
}
//prints 5, 4, 3, 2

Hope this helps!
If not, please tell me which language you need it for!

Answer 4

//to loop backward in PHP is very easy. So, use this example:
<?php
function samp(){
$example = 10;
while($example > 1){
$example--;
echo $example."<br>";
if($example ==1){
echo "time up!";
}
}
}
samp();
?>
