For printing 0 to 9

​

you can write like below also

var i;

for (i = 0; i < 10; i++) {

  console.log(i);

}

for (i in things) {

    // If things is an array, i will usually contain the array keys *not advised*

    // If things is an object, i will contain the member names

    // Either way, access values using: things[i]

}

const numbers = [3, 4, 8, 9, 2];

for (let i = 0; i < numbers.length; i++) {

    const accessNumbers = numbers[i];

    console.log(accessNumbers);

}

//Expected output:3 4 8 9 2

for (let a = 0; a < 10; a++) {

    console.log(a);

}

for( initialization of expression; condition; action for initialized expression ) {

  instruction statement to be executed;

}

let i = 0;

do {

  i += 1;

  console.log(i);

} while (i < 5);
