If you did try to "pause" by looping, then you'd essentially "hang" the Javascript interpreter for a period of time. Instead, any code that you want to run delays must be inside the setTimeout() callback function (or called from that function). You cannot just pause javascript execution for a predetermined amount of time. It will not wait until after the timeout fires in the stateChange() function. The console.log() statement will run immediately. function wait(ms)īut, if you have code like this: stateChange(-1) However, if in some non-production case you really want to hang the main thread for a period of time, this will do it. Joseph Silber has demonstrated that well in his answer.
You really shouldn't be doing this, the correct use of timeout is the right tool for the OP's problem and any other occasion where you just want to run something after a period of time.
