KA ProcessingJS Max Infinite Loop Count is Too Short

How can we help?

Right now it is extremely difficult to get even relatively basic simulations to run in Khan Academy's ProcessingJS editor without going over the _env_.KAInfiniteLoopCount limit, causing the project to freeze and display an error message saying that a loop is taking too long to run.

Early into the development of my current project, I ran into this problem, and I had to solve it with a really annoying workaround: I made it so that if you click on the screen, it tells the draw function to stop looping, then immediately start looping again.

The way I propose this problem be fixed is by adding the ability to modify the limit variable, at least up to maybe 5000 iterations, aka 5 times the current limit. Maybe even make an option to ignore some errors, such as '==' not being allowed at all.

There are some workarounds to the limit, but I'd love a higher limit by default

KWC made a function that very easily lets you increase the max infinite loop time.

/** @CREDIT created by MKaelin368 (KWC) (c) 2018 */
function setKALoopTimeout (ms) {
  var method_name = 'KAInfiniteLoopSetTimeout';
  if (method_name in this) {
    this[method_name](ms >>> 0);
  }
}

// sets max loop time to 5000 milliseconds
setKALoopTimeout(5000);

You also can use jshint commands to make oh noes ignore double equal signs

// the following comment causes jshint to ignore double equal signs (and also a bunch of other stuff)
// jshint ignore: start
if ("hello" == "hello") {
  println("hello");
}
