Fibonacci series in  JavaScript var limit = prompt("Enter the limit 'n' to generate the Fibonacci  series:", " "); var f1=0; var f2=1; document.write("The limit entered to generate the Fibonacci  series is: ",limit, "<br/>"); document.write("The Fibonacci  series is: "); document.write("",f1," "); document.write("",f2," ");   var i,f3; for(i=2; i<limit; i++) { f3=f1+f2; document.write("",f3,", "); f1=f2; f2=f3; } OutPut : The limit entered to generate the Fibonacci series is: 20 The Fibonacci series : 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 The limit entered to generate the Fibonacci series is: 15 The Fibonacci series : 0 1 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377,
