The kids who participated in the study regularly slept between eight and 11 hours a night and were considered generally healthy, the study said.Īfter one week of receiving 39 minutes less of sleep per night, the children reported lower overall well-being and ability to cope at school, the study said. Set bedtime back to prepare your child for kindergarten, study says So, looping waiting for some variable to change will never work because no other code can run to change that variable.Mixed race girl reading book - stock photo Inti St Clair/Tetra images RF/Getty Images ![]() Because Javascript runs your code in only a single thread, when you're looping nothing else can run (no other event handlers can get called). 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. ![]()
