These are some examples of simple for loop challenges and exercises I did for fun.
// Print 'hello' the string vertically var str = 'hello'; for(var count = 0; count < str.length; count++) { console.log(str[i]) } // print all numbers between -10 and 19 for(var i = -10; i < 20; i++) { console.log(i) } // print even numbers between 10 and 40 for(var i = 10; i < 40; i++) { if(i % 2 === 0){ console.log(i) } } // print all odd numbers between 300 and 333 for(var i = 300; i < 333; i++) { if(i % 3 === 0){ console.log(i) } } // print all numbers divisible by 5 and 3 between 5 and 50 for(var i = 5; i < 50; i++) { if(i % 3 === 0 && i % 5 === 0) { console.log(i) } }
