2020-3-27 native JS / ZL8: for loop descending and ascending

1, in descending order -> for (var = timeOrder.length I-1; I> = 0; I -) {// ... 56 is 0
IF (timeOrder [I] .time <= thistime) {
IF (isFirst = I! ) {
boarddis (I);
isFirst = I;
}
BREAK;
}
}
2, ASC -> for (var I = 0; I <timeOrder.length; I ++) {// ... 56 is 0
IF (timeOrder [I]. Time => thistime) {
! IF (isFirst = I) {
boarddis (I);
isFirst = I;
}
BREAK;
}
}
. 3, in the process of understanding the JS for cycle may be understood
descending: first descending after ascending order;
ascending: ascending first, after ascending;
