Loops

Let's explore loops!

Explore:

1. Change the numbers in each of these loops to see how it affects the output.
2. Write your own while, do...while, and for loop.

// This is a while loop
let i = 0;
while (i < 4) {
  console.log('This piece of code ran. i equals: ' + i);
  i++;
}

// This is a do...while loop
let i = 0;
do {
  console.log('This piece of code ran. i equals: ' + i);
  i++;
} while (i < 4)

// This is a for loop
for (let i = 0; i < 4; i++) {
  console.log('This piece of code ran. i equals: ' + i); 
}
// This is a for loop going in the opposite direction
for (let j = 10; j > 0; j--) {
  console.log('This piece of code ran. i equals: ' + i); 
}
// Note that i is a variable so you can rename it any valid variable name.
// i is a common name for an iterator variable. If you already have an i variable j is also common.
for (let thisIsAVariableYouCanNameItWhateverYouWant = 0; thisIsAVariableYouCanNameItWhateverYouWant < 2; thisIsAVariableYouCanNameItWhateverYouWant++) {
  console.log('This piece of code ran. thisIsAVariableYouCanNameItWhateverYouWant equals: ' + thisIsAVariableYouCanNameItWhateverYouWant); 
}
