Let’s combine all that we’ve learned so far:

• variables, operators, and data types
• functions and control flow
• lists and loops

Examples of for and while loops are provided below in JavaScript. Copy each one to the editor and run it! You’ll see that they do the same things.

In this for loop, the instructions are run 10 times.

for (i = 0; i < 10; i++) {
  placeTile('mint')
  placeTile('orange')
  placeTile('mint')
}

In this while loop, we create a counter at 0 and add 1 to it every iteration. The loop is executed until the counter is 10 or more.

let i = 0;
while (i < 10) {
  placeTile('mint')
  placeTile('orange')
  placeTile('mint')
  i++
}
