possible bug clearInterval

possible bug in this code
bad code

function parpadeo(time)
{
clearInterval(inter1);
var  l = false;
var inter1 = setInterval(function() {
 l = !l;
  C1.write(l);
}, time);
}

parpadeo(200);
function led1(time1)
{
clearInterval(led2);
var  l1 = false;
var led2 = setInterval(function() {
 l1 = !l1;
  A1.write(l1);
}, time1);
}
led1(300);

desired effect

function parpadeo(time)
{
//clearInterval(inter1);
var  l = false;
var inter1 = setInterval(function() {
 l = !l;
  C1.write(l);
}, time);
}

function led1(time1)
{
//clearInterval(led2);
var  l1 = false;
var led2 = setInterval(function() {
 l1 = !l1;
  A1.write(l1);
}, time1);
}
parpadeo(200);
led1(300);

all this with tested stm32 f3 dicovery and espruino 1v61
you will obtain a different result.

I hope to be of help
Thank you greetings
