Question

Can I pause execution from within JS code? I am working on a simple haxe-based debug util, and I want to be able to simulate breakpoints, by calling a util method which will trigger the execution pause.

Not sure if this is what you’re looking for, but in Chrome (and Firefox if Firebug is installed) you can use the built-in JavaScript debugger statement. This causes the execution to pause, and is effectively like setting a breakpoint. For example, the following would break on every iteration of the loop allowing you to examine the value of i (stupidly simple example):

for(var i = 0; i < 10; i++) {
    debugger;
    console.log(i);
}
