Javascript – Simple For Loop Examples

// 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)
 }
}
