Once you clear the interval using clearInterval you could setInterval once again  And to avoid repeating the callback externalize it as a separate function   var ticker   function         console log  idle         then   var myTimer   window setInterval ticker  4000     then when you decide to restart   window clearInterval myTimer   myTimer   window setInterval ticker  4000

If by  restart   you mean to start a new 4 second interval at this moment  then you must stop and restart the timer   function myFn    console log  idle      var myTimer   setInterval myFn  4000       Then  later at some future time      to restart a new 4 second interval starting at this exact moment in time clearInterval myTimer   myTimer   setInterval myFn  4000       You could also use a little timer object that offers a reset feature   function Timer fn  t        var timerObj   setInterval fn  t        this stop   function             if  timerObj                clearInterval timerObj               timerObj   null                    return this                start timer using current settings  if it s not already running      this start   function             if   timerObj                this stop                timerObj   setInterval fn  t                     return this                start with new or original interval  stop current interval     this reset   function newT   t            t   newT          return this stop   start              Usage   var timer   new Timer function            your function here    5000        switch interval to 10 seconds timer reset 10000       stop the timer timer stop        start the timer timer start      Working demo  https   jsfiddle net jfriend00 t17vz506
