A question about how to use khash.h

[pcaparser]

I wrote the following code, kh_put -> kh_del -> kh_put

KHASH_MAP_INIT_INT(1, int) KHASH_MAP_INIT_INT(2, int) int main() { int ret; khiter_t k; khiter_t j; khash_t(1) h = kh_init(1); khash_t(2) i = kh_init(2);

int x = 0, y = 0;
for (; x < 100; x++)
{
    k = kh_put(1, h, x, &ret);
    kh_value(h, k) = x;

    j = kh_put(2, i, x, &ret);
    kh_value(i, j) = x + 1;
}

printf("h size:%d, i size: %d\n", kh_size(h), kh_size(i));

for (x = kh_begin(h); x < kh_end(h); x++)
{
    kh_del(1, h, x);
}

for (x = kh_begin(i); x < kh_end(i); x++)
{
    kh_del(2, i, x);
}

printf("h size:%d, i size: %d\n", kh_size(h), kh_size(i));

for (; x < 100; x++)
{
    k = kh_put(1, h, x, &ret);
    kh_value(h, k) = x;

    j = kh_put(2, i, x, &ret);
    kh_value(i, j) = x + 1;
}
printf("h size:%d, i size: %d\n", kh_size(h), kh_size(i));
return 0;

}

expect the result should be h size:100, i size: 100 h size:0, i size: 0 h size:100, i size: 100

but got: h size:100, i size: 100 h size:0, i size: 0 h size:0, i size: 0

can anyone tell me what's the problem? thanks.

Is there javascript analog new Set or new Map?
